Convert binomial to linear regression
bin2lin(D, doplot = FALSE)
standard format coloc dataset
plot results if TRUE - useful for debugging
D, with original beta and varbeta in beta.bin, varbeta.bin, and beta and varbeta updated to linear estimates
Estimate beta and varbeta if a linear regression had been run on a binary outcome, given log OR and their variance + MAF in controls
sets beta = cov(x,y)/var(x) varbeta = (var(y)/var(x) - cov(x,y)^2/var(x)^2)/N
