A new and improved version of FFBSKAT is now a part of the FREGAT R package available on CRAN FREGAT R package supplies the most common and efficient tests for the region-based association analysis aimed at identification of rare genetic variants for family-based, genetically related or population samples. Along with FFBSKAT and FFBSKAT optimal, burden tests and functional linear models are implemented.
FFBSKAT is an efficient tool for region/gene association analysis of quantitative traits in samples of related individuals. This software is an exact implementation of sequence kernel association test based on the kernel machine regression for familial data described in Schifano et al. , Chen et al. , Oualkacha et al. .
DOWNLOADS (Please use FREGAT package for newer version of FFBSKAT() function!):
