Hi,

Perhaps a naive question, but it's just not clear to me. From the adapted FaST-LMM program EWASher I get this output.

What are the effect size (beta), and corresponding standard error? Is that SnpWeight, or OddsRatio? If I calculated exp(-0.2938), I do not get OddsRatio=2.272, conversely if I do ln(2.272) it's not immediately clear to which column this corresponds? The model I used contained a couple of covariates, perhaps the OddsRatio is that of the full model, and SnpWeight is that of the model without covariates, or vice versa?

It's not immediately clear to from the paper either.

Thanks and best,

Sander
