FastPval Description

FastPval is a multiple stage p-value computing software that computes empirical p-values from a large set of permutated/resampled background data. To find the p-value from the background, traditional "exact" method needs to sort and search from the whole dataset. It's usage is usually hampered by computing speed, storage and memory limitation when the sample size is too big. FastPval was developed aiming to solve these problems. The main idea of FastPval is to separate the large dataset into smaller parts based on user specified p-value, build model for each part, and calculate the p-values with different model according to the score. Give FastPval a try to see what it's really capable of! Main features: Is flexible enough to produce model files and quick to compute P-value; Is efficient enough to store two approximate models for reduplicated P-value computation without loading all raw dataset; Allow visible GUI interface for the functions of model generating, two stage P-value computation and exact P-value computation using traditional method; Is compact enough for model size without loading the whole dataset into memory;
