Dear All,

I conducted a factorial experiment. My factors are A (4-levels), B (2-levels) and C (2-levels) in 4 blocks. Factor A is different genotypes of a plant. I measured different traits in this experiment.

I want to put my measurements in a model and I want to remove the variation of factor A from my data response. Can I do it?

I saw a method about it in a paper. They analyzed the response of data (ex. Biomass) to Factor A. Then they saved the residuals and used them as new variables (biomass without the factor A variation). Is it possible?

Thank you so much

🙏
