Genet., 2016)](cfw.gif) + +Features include: + ++ Fast assocation tests implemented using the univariate linear mixed +model (LMM). In GWAS, this can correct for account for population +stratification and sample nonexchangeability. It also provides +estimates of the proportion of variance in phenotypes explained (PVE) +by available genotypes (often called "chip heritability" or "SNP +heritability"). + ++ Fast association tests for multiple phenotypes implemented using a +multivariate linear mixed model (lvLMM). + +It fits a multivariate linear mixed model (mvLMM) for testing marker +associations with multiple phenotypes simultaneously while controlling +for population stratification, and for estimating genetic correlations +among complex phenotypes. + ++ It fits a Bayesian sparse linear mixed model (BSLMM) using Markov +chain Monte Carlo (MCMC) for estimating PVE by typed genotypes, +predicting phenotypes, and identifying associated markers by jointly +modeling all markers while controlling for population structure. + ++ It estimates variance component/chip heritability, and partitions it +by different SNP functional categories. In particular, it uses HE +regression or REML AI algorithm to estimate variance components when +individual-level data are available. It uses MQS to estimate variance +components when only summary statisics are available. + +*Add note here about posting questions, comments or bug reports to +Issues.* + +### Citing GEMMA + +*Add text here.* + +### License + +Copyright (C) 2012–2017, Xiang Zhou. + +### Quick start + +*Add text here.* + +### Setup + +*Add text here.* + diff --git a/cfw.gif b/cfw.gif new file mode 100644 index 0000000..d85e375 Binary files /dev/null and b/cfw.gif differ
