The scree plot shows the … In statistics, collinearity refers to a linear relationship between two explanatory variables. Two variables are perfectly collinear if there is an exact linear relationship between the two, so the correlation between them is equal to 1 or −1. That is, X1 and X2 are perfectly collinear if there exist parameters and such that, for all observations i, we have This means that if the various observations (X1i, X2i) are plotted in the (X1, X2) plane, these poi… forward air cst tracking https://mcmanus-llc.com
