WebThe group variable sets the first 100 elements to be in level ‘1’ and the next 100 elements to be in level ‘2’. We can plot the combined data: plot(y ~ x, col=as.integer(group), pch=19, las=1) Here group 1 data are plotted with col=1, which is black. Group 2 data are plotted with col=2, which is red. WebJan 1, 2014 · The usual procedure then is to include x 1ij as well as \(\bar{{x}}_{1.j}\) among the explanatory variables with fixed effects. This allows separate estimation of the within-group regression (the coefficient of x 1ij) and the between-group regression (the sum of the coefficients of x 1ij and \(\bar{{x}}_{1.j}\))..

"WebThe regression equation will look like this: Height = B0 + B1*Bacteria + B2*Sun + B3*Bacteria*Sun. Adding an interaction term to a model drastically changes the interpretation of all the coefficients. Without an interaction term, we interpret B1 as the unique effect of Bacteria on Height. But the interaction means that the effect of Bacteria … " - Grouping regression
