I ran a multiple linear regression to check the relationship between methylation and cortisol.
When I extract the results I have a significant site (p-value) but the coefficients are really small. I am having trouble interpreting the results. Would that mean that this has no practical significance (cause the estimates are very small)?
Or do I need to standardize the independent variable (x = cortisol) that I have used? (if I have to standardize, can you please recommend how to do it via limma)
