Estimating variance components of groups of covariates within regression model
...7,-0.52) Y = c(1.4,2.75,1.4,1.94,2.11,2.44,1.94,1,2.11,1.4) model = lm(Y ~ L_F + L_W + R_A + R_W + C_U + C_F) I want to identify how much of the variance is attributable to L, R, and C - three groups each having two covariates in the model. While I find several examples that apply lmer, aov, or CorVarr functions to estimate variance components, I don't see how to apply these to my design. I both don't see how to block my data so that I can run aov, nor do I see how to do so from within the linear regression model, as other examples (that I find) are purely repeat measures or specifical...
