calc_f_stat: Calculate F-statistic

In jwr-git/mrpipeline: Implements a Ready-for-Use Mendelian Randomisation Pipeline

Calculate F-statistic

Description

Calculates portion of variance explained and F-statistic. If the data is lacking key information, i.e. allele frequencies, sample size or consists of only one SNP, then the approximate F-statistic will be used instead: F = b ** 2 / SE ** 2.

Usage

calc_f_stat(dat, f_cutoff = 10, force_approx = FALSE, verbose = TRUE)

Arguments

dat	Data.frame from do_mr()
f_cutoff	F-statistic cutoff (Optional)
force_approx	Force to use the approximate F-statistic instead (Optional, boolean)
verbose	Display verbose information (Optional, boolean)

Value

Modified 'dat' data.frame (if f_cutoff > 0 supplied)
