Full collinearity test
Web2. You can test that three 2D points, a, b, and c, fall on a line by noting the slope of line segment ( a, b) will have to be the same as that of ( b, c ), or by noting that the area of the triangle they define will be zero if and only if the three points are collinear. I chose the former method because the math seemed more concise: this answer ... WebA VIF value >10 generally indicates to use a remedy to reduce multicollinearity. 2 The easiest approach is to recognize the collinearity, drop one or more of the variables from the model, and then interpret the regression analysis accordingly. 4. McIsaac et al 1 used Bayesian logistic regression modeling. Frequentist approaches to linear ...
