Software

unihtee

unihtee implements nonparametric inference procedures for treatment effect modification variable importance parameters. These variable importance parameters reflect individual confounders’ capacity for treatment effect modification and are suited for high-dimensional data with potentially complex correlation structures.

uniCATE

uniCATE implements semiparametric inference procedures for variable importance parameters that assess biomarkers’ treatment effect modification capabilities in high-dimensional clinical trials.

cvCovEst

The cvCovEst R package implements a data-adaptive framework for asymptotically optimal covariance matrix estimator selection in high dimensions.

scPCA

The scPCA R package implements sparse contrastive PCA, a variant of PCA that extracts sparse, stable, and interpretable signal.
