At the time, addicts were lucky to find a hospital bed to detox in. A hundred years ago, the federal government began the drug war with the Harrison Act, which effectively criminalized heroin and other narcotics. Doctors were soon barred from addiction maintenance, until then a common practice, and hounded as dope peddlers.
Bayesian structural time series (BSTS) model is a statistical technique used for feature selection, time series forecasting, nowcasting, inferring causal impact and other applications. The model is designed to work with time series data. The model has also promising application in the field of analytical marketing. In particular, it can be used ...
There are many statistical packages that can be used to find structural breaks, including R, [17] GAUSS, and Stata, among others.For example, a list of R packages for time series data is summarized at the changepoint detection section of the Time Series Analysis Task View, [18] including both classical and Bayesian methods.
CRAFT is a motivational model of family therapy. [5] It is reward-based [5] —that is, based on positive reinforcement. CRAFT is aimed at the families and friends of treatment-refusing individuals who have a substance use disorder. [5] "CRAFT works to affect [influence] the substance users' behavior by changing the way the family interacts ...
SMART Recovery is based on scientific knowledge and is intended to evolve as scientific knowledge evolves. [4] The program uses principles of motivational interviewing, found in motivational enhancement therapy (MET), [5] and techniques taken from rational emotive behavior therapy (REBT), and cognitive-behavioral therapy (CBT), as well as scientifically validated research on treatment.

Given a time series of data x t, the STAR model is a tool for understanding and, perhaps, predicting future values in this series, assuming that the behaviour of the series changes depending on the value of the transition variable. The transition might depend on the past values of the x series (similar to the SETAR models), or exogenous variables.
The CRAN task view on Time Series contains links to most of these. Mathematica has a complete library of time series functions including ARMA. [11] MATLAB includes functions such as arma, ar and arx to estimate autoregressive, exogenous autoregressive and ARMAX models. See System Identification Toolbox and Econometrics Toolbox for details.
