Version 3.1.0 of sate, the software package for analyzing jury trials, is now available on CRAN. The package allows users to perform analysis with R, a free, open-source application for data analysis and graphing. Version 3.1.0 is a major update for faster, more precise solutions. It also features exciting new tools for analyzing trials with ordered outcomes, like charges with lesser included offenses.
See what’s new in v 3.1.0.
- Updated get_pG_by_k function. Implemented analytic method for obtaining guilty/death verdict probabilities given jury size. The analytic solution is based on matrix algebra, not simulation or use of while loop. Improved function used by analysis functions for faster and more precise results.
- Added transition.matrix function. It returns a transition probability matrix for jury deliberating choice between NG and G verdicts.
- Added transition.matrix.ordered function. It generates a transition probability matrix for jury deliberating choice among three or more ordered verdict options.
- Added prob.ordered.verdicts function. It obtain the final (absorbing) state probabilities for jury deliberating among three or more ordered verdict options. This function calls the transition.matrix.ordered function (which may also be called as stand alone function).
- Added prob_ord_from_pool function. Given verdict preferences in population from which jurors are selected, it returns deliberated verdict probabilities for trial jury deliberating among three or more ordered verdict options. This function calls the transition.matrix.ordered and prob.ordered.verdicts functions (which may also be called as stand alone functions).
