when do you use two variables with multicollinearity what type of intervals do you use to test for multicollinearity can you use the age as the interval in a regression model can multicollinearity be used with age and birthday do you use age at test as part of multicollinearity what's the multicollinearity of a regression model can you do multicollinearity over intervals how to find multicollinearity what type of relationship is multicollinearity which variable has the highest multicollinearity when you use multicollinearity over intervals is multicollinearity constant when x and a is a constant, is multicollinearity still valid what is multicollinearity in regression when two variables are constant in multiple linearity model can you use age at the test and birthday in a regression model? how? when does multicollinearity occur when does multicollinearity occur over intervals when do you have multicollinearity is multicollinearity always over intervals
