Observations: 20 Variables: 8 In multiple regression, the variance inflation factor (VIF) is used as an indicator of multicollinearity. Computationally, it is defined as the reciprocal of tolerance: 1 / (1 - R2). All other things equal, researchers desire lower levels of VIF A simple approach to identify collinearity among explanatory variables is the use of variance inflation factors (VIF). VIF calculations are straightforward and easily comprehensible the higher the value, the higher the collinearity. I am getting the following error when calculating VIF on a small dataset in Rstudio.
