There may be slight differences between provisional and final data for a given data year (e.g., 2021). Final drug overdose death data published annually through NCHS statistical reports (8) and CDC WONDER are typically tabulated by state of residence and limited to residents of the United States. Provisional data, such as the Drug Overdose Death Counts released through the Vital Statistics Rapid Release (VSRR) program, include all deaths that occurred within the 50 states and the District of Columbia, including foreign residents. As such, provisional counts include approximately 400-500 additional drug overdose death records where the decedents were not US residents. Provisional data are tabulated by state of occurrence to capture the burden on the place where the deaths occur, and to correspond to the various data quality metrics that are provided.

SPSS Statistics is a statistical software suite developed by IBM for data management, advanced analytics, multivariate analysis, business intelligence, and criminal investigation. Long produced by SPSS Inc., it was acquired by IBM in 2009. Current versions (post 2015) have the brand name: IBM SPSS Statistics.
SPSS is a widely used program for statistical analysis in social science.[6] It is also used by market researchers, health researchers, survey companies, government, education researchers, marketing organizations, data miners,[7] and others. The original SPSS manual (Nie, Bent & Hull, 1970)[8] has been described as one of "sociology's most influential books" for allowing ordinary researchers to do their own statistical analysis.[9] In addition to statistical analysis, data management (case selection, file reshaping, creating derived data) and data documentation (a metadata dictionary is stored in the datafile) are features of the base software.
The graphical user interface has two views which can be toggled by clicking on one of the two tabs in the bottom left of the SPSS Statistics window. The 'Data View' shows a spreadsheet view of the cases (rows) and variables (columns). Unlike spreadsheets, the data cells can only contain numbers or text, and formulas cannot be stored in these cells. The 'Variable View' displays the metadata dictionary where each row represents a variable and shows the variable name, variable label, value label(s), print width, measurement type, and a variety of other characteristics. Cells in both views can be manually edited, defining the file structure and allowing data entry without using command syntax. This may be sufficient for small datasets. Larger datasets such as statistical surveys are more often created in data entry software, or entered during computer-assisted personal interviewing, by scanning and using optical character recognition and optical mark recognition software, or by direct capture from online questionnaires. These datasets are then read into SPSS.
SPSS Statistics launched version 25 on Aug 08, 2017. SPSS v25 adds new and advanced statistics, such as random effects solution results (GENLINMIXED), robust standard errors (GLM/UNIANOVA), and profile plots with error bars within the Advanced Statistics and Custom Tables add-on. V25 also includes new Bayesian Statistics capabilities, a method of statistical inference and publication ready charts, such as powerful new charting capabilities, including new default templates and the ability to share with Microsoft Office applications.[10]
Using the procedures in IBM SPSS Neural Networks, you can develop more accurate and effective predictive models. The result? Deeper insight and better decision making.What is a neural network?A computational neural network is a set of non-linear data modeling tools consisting of input and output layers plus one or two hidden layers. The connections between neurons in each layer have associated weights, which are iteratively adjusted by the training algorithm to minimize error and provide accurate predictions.
Complement traditional statistical techniquesThe procedures in IBM SPSS Neural Networks complement the more traditional statistics in IBM SPSS Statistics Base and its modules. Find new associations in your data with Neural Networks and then confirm their significance with traditional statistical techniques
How can you use IBM SPSS Neural Networks?You can combine Neural Networks with other statistical procedures to gain clearer insight in a number of areas:
Over three-quarters of DWI offenders in jail reported using drugs in the past. Among jail inmates held for DWI, marijuana (73%) and cocaine-based drugs including crack (41%) were the most commonly used drugs. Thirty percent of those in jail reported drug use in the month prior to arrest.
In 1991, 60% of federal prisoners reported prior drug use, compared to 79% of state prisoners. In 1997 this gap in prior drug use was narrowed, as the percentage of federal inmates reporting past drug use rose to 73%, compared to 83% of state inmates. By 2004 this gap was almost closed, as state prisoner reports of lifetime drug use stayed at 83%, while federal inmates rose to 79%. This increase was mostly due to a rise in the percentage of federal prisoners reporting prior use of marijuana (from 53% in 1991 to 71% in 2004), cocaine/crack (from 37% in 1991 to 44% in 2004), and hallucinogens (from 15% in 1991 to 26% in 2004).
The proportion of state prison inmates reporting the past use of cocaine or crack declined slightly between 1997 (49%) and 2004 (47%). Marijuana use (78%) remained stable since 1997 (77%), and remained the most commonly used drug. Past use of opiates, including heroin (23%) remained almost unchanged since 1997 (24%). Past use of methamphetamine rose from 19% in 1997 to 23% in 2004.
In 1997 mothers in state prison were more likely than fathers to report drug use in the month before their offense: 65% for mothers and 58% for fathers. Cocaine/crack was the most common drug used: 45% for mothers and 26% for fathers.
The rule goes into effect 120 days from the date of publication in the Federal Register, and once implemented, will address the proliferation of these un-serialized firearms in several ways. These include:
License keys are the defacto-standard as an anti-piracy measure. To be honest, this strikes me as (in)Security Through Obscurity, although I really have no idea how license keys are generated. What is a good (secure) example of license key generation? What cryptographic primitive (if any) are they using? Is it a message digest? If so, what data would they be hashing? What methods do developers employ to make it difficult for crackers to build their own key generators? How are key generators made?
One solution that should give you these would be to use a public key signing scheme. Start with a "system hash" (say grab the macs on any NICs, sorted, and the CPU-ID info, plus some other stuff, concatenate it all together and take an MD5 of the result (you really don't want to be handling personally identifiable information if you don't have to)) append the CD's serial number and refuse to boot unless some registry key (or some datafile) has a valid signature for the blob. The user activates the program by shipping the blob to you and you ship back the signature.
Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)
A good software license key/serial number generator consists of more than just a string of random characters or a value from some curve generator. Using a limited alphanumeric alphabet, data can be embedded into a short string (e.g. XXXX-XXXX-XXXX-XXXX) that includes all kinds of useful information such as:
However, despite being broken up into steps, this falls prey to the same methods of cracking used for the normal process. The process used to create an activation key that is checked against the original CD key was quickly discovered, and generators that incorporate both of the keys were made.
Most secure schemes involve either the user providing the software supplier with some details of the machine which will run the software (cpu serial numbers, mac addresses, Ip address etc.), or, require online access to register the software on the suppliers website and in return receive an activitation token. The first option requires a lot of manual administration and is only worth it for very high value software, the, second option can be spoofed and is absolutly infuriating if you have limited network access or you are stuck behind a firewall.
Perform Weighted Fitting using either Levenberg-Marquardt or Orthogonal Distance Regression algorithms. The latter supports weights for both X and Y data. Select from over 12 weighting methods including instrumental, statistical, direct, arbitrary dataset, and variance.

Rates of drug-related poisoning were 60.9% higher in 2020 (79.5 deaths per million) than they were in 2010 (49.4 per million). The rate has increased every year since 2012; the increase from 2019 was not statistically significant.
Males accounted for more than two-thirds of registered drug poisonings in 2020 (3,108 male deaths compared with 1,453 female deaths), consistent with previous years. The male age-standardised rate increased from 104.7 deaths per million in 2019 to 109.7 in 2020, while the female age-standardised rate increased from 49.1 per million in 2019 to 49.8 in 2020. Neither change was statistically significant. 2ff7e9595c
