fstats: A function for quickly calculating f statistics for use in sva
Description
This function does simple linear algebra to calculate f-statistics
for each row of a data matrix comparing the nested models
defined by the design matrices for the alternative (mod) and and null (mod0) cases.
The columns of mod0 must be a subset of the columns of mod.
Usage
fstats(dat, mod, mod0)
Arguments
dat
The transformed data matrix with the variables in rows and samples in columns
mod
The model matrix being used to fit the data
mod0
The null model being compared when fitting the data
Value
fstats A vector of F-statistics one for each row of dat.
