genomic.inflation.factor R Documentation
Evalutes the genomic inflation factor (lambda)
Description
Evalutes the genomic inflation factor (lambda) for genome-wide association studies.
In details, lambda is the observed median value of the chi-squared statistic for the
null markers divided by the expected median value of the chi-squared statistic
(approximately 0.456 for 1 degree of freedom tests).
Usage
genomic.inflation.factor(values, type = "pvalue")
Arguments
values
the statistic distribution
type
statistic distribution (allowed: zscore, chisq, pvalue – default: pvalue)
Value
the "inflation factor" lambda
Author(s)
Alessia Visconti
Examples
pvalues <- abs(rnorm(1000, mean=0.001, sd=0.1))
genomic.inflation.factor(pvalues, "pvalue")
