A platform for calculating genotypic predictors of binary and quantitative phenotypes

A program to impute SNP genotypes from ultra-low coverage whole genome sequencing data

A program to model admixture using ancestry-informative markers

To calculate the sample size required to learn to classify with a high-dimensional biomarker panel, an online sample size calculator is available.

Consider a guide to using the online calculator. The statistical methods are described in this paper.

This paper proposes that the expected information for discrimination (expected weight of evidence) should supplant the C-statistic (area under the ROC curve) for quantifying the performance of a diagnostic test or risk predictor, and for evaluating the incremental contribution of a new biomarker. The wevid R package is available to calculate and plot the distributions of weights of evidence. A tutorial on using the package and interpreting the results is also available.
