Psaboot Jason Bryer Site created with quarto by jason bryer. r package and shiny application for the analysis of qualitative data. The methods parameter on the psaboot function specifies the different propensity score methods that will be used. specifically, for each bootstrap sample drawn, each function will be called.
Jason Bryer Ph D Jason Bryer With the wide availability of high power computers resampling methods such as bootstrapping (efron, 1979) have become popular for providing more estimates of the sampling distribution. this paper introduces the psaboot r package that provides functions for bootstrapping propensity score methods. The psaboot function returns an object of class psaboot. the following s3 methods are implemented: print, summary, plot, boxplot, and matrixplot. By default, bootstrapping using two classification tree methods (using 'rpart' and 'ctree' functions), two matching methods (using 'matching' and 'matchit' packages), and stratification with logistic regression. a framework is described for users to implement additional propensity score methods. With psa, particularly in the stratification section, it is possible to tease out how an intervention may vary by the observed covariates. i have taught psa many times over the years. this “book” is my attempt to collect my notes and experiences on conducting psa.

Jason bryer assistant professor and associate director, data science and information systems, school of professional studies, cuny. This paper explores the effects of matching order using the psaboot package for bootstrapping propensity score analysis using two of the more popular r packages for matching, matchit (ho, imai, king, & stuart, 2011) and matching (sekhon, 2011). Returns balance for each covariate from propensity score matching. description this function is function is primarily used by [psaboot::balance ()] and probably does not need to be called directly.
