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

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

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.
