In MRCIEU/TwoSampleMR: Two Sample MR Functions and Interface to MR Base Database

Estimate trait SD by obtaining beta estimates from z-scores and finding the ratio with original beta values

Description

Assumes that sample size and allele frequency is correct for each SNP, and that allele frequency gives a reasonable estimate of the variance of the SNP.

Usage

estimate_trait_sd(b, se, n, p)

Arguments

b	vector of effect sizes.
se	vector of standard errors.
n	vector of sample sizes.
p	vector of allele frequencies.

Value

Vector of sd estimates for each association.
