WebSep 19, 2024 · I found it very hard to estimate GWAS filtered by "feeling" and looking at plots (also because I want to do it automatically). I am new to GWAS and all I need is a simple GWAS. I was unsure about using PCA or LMM or I could go for a simple linear analysis and whether this looks kind of "normal".Thanks for your feedback. $\endgroup$ – WebLinear regression.
