Compute Approximate F-statistic from GWAS Summary Statistics

Computes the approximation F = (beta_ZX / se_ZX)^2 for each SNP. This is the standard approximation used when individual-level data is not available.

Usage

computeApproxFStatistic(betaZX, seZX)

Arguments

betaZX

Numeric vector of SNP-exposure effect estimates.

seZX

Numeric vector of standard errors for SNP-exposure effects.

Value

Numeric vector of approximate F-statistics.

Examples

computeApproxFStatistic(c(0.5, 0.3), c(0.05, 0.1))
