For this first presentation in PolBeRG, Juraj Medzihorsky will present version 0.5 of a R package which has been under active development for the past 1-2 years. Juraj is a PhD candidate in Political Science at CEU, where his work focuses on think tanks in post-communist countries (more information can be found here: http://pds.ceu.hu/sites/default/files/field_profile_cv/user-[uid]/medzihorsky_cv_short.pdf). To put it briefly, 'pistar' implements the π* mixture index of fit. This is a new measure of model fit which is easy to interpret, applies easily to many different models, and unlike conventional measures of fit it rests on assumptions that are always true. The short presentation will be followed by a workshop. Juraj welcomes bringing your own data and/or problems and see if the mixture index of fit can help. You can install ‘pistar’ from R using package ‘devtools’. Simply install ‘devtools’ and run library(devtools) install_github("pistar", username="jmedzihorsky") You can find a copy of the manual at https://github.com/jmedzihorsky/pistar/blob/master/pistar_0.5.2_manual.pdf
