The R package and webtool fits Prevalence Incidence Mixture models to leftcensored and irregularly intervalcensored time to event data that is commonly found in screening cohorts assembled from electronic health records. Absolute and relative risk can be estimated for simple random sampling, and stratified sampling (the two approaches of superpopulation and a finite population are supported for target populations). Nonparametric (absolute risks only), semiparametric, weaklyparametric (using Bsplines), and some fully parametric (such as the logisticWeibull) models are supported.

This R package can be used to calculate the required samples size for unconditional multivariate analyses of unmatched casecontrol studies. The sample sizes are for a scalar exposure effect, such as binary, ordinal or continuous exposures. The sample sizes can also be computed for scalar interaction effects. The analyses account for the effects of potential confounder variables that are also included in the multivariate logistic model.
