Truncated Multivariate Normal Simulation (tmvnsim)
Importance sampling from the truncated multivariate normal using the GHK (Geweke-Hajivassiliou-Keane) simulator. Unlike Gibbs sampling which can get stuck in one truncation sub-region depending on initial values, this package allows truncation based on disjoint regions that are created by truncation of absolute values. The GHK algorithm uses simple Cholesky transformation followed by recursive simulation of univariate truncated normals hence there are also no convergence issues. Importance sample is returned along with sampling weights, based on which, one can calculate integrals over truncated regions for multivariate normals.
The Irvine Robustness Assessment for Qualitative Comparative Analysis (iaQCA)
Test the robustness of the QCA method, or a user’s QCA solutions, to randomness. iaQCA is also packaged with the irQCA function, which provides recommendations for improving QCA solutions to reach typical significance levels.
Blinder-Oaxaca Decomposition for Generalized Linear Model (GeneralOaxaca)
Perform the Blinder-Oaxaca decomposition for generalized linear model with bootstrapped standard errors. The twofold and threefold decomposition are given, even the generalized linear model output in each group.
