why does the mean of an independent variable change how is multicollinearity calculated? what is the difference between an independent variable and an independent variable can u shaped relationships be replicated? why do the independent variables of a curve have a positive correlation what is the solution to the multicollinearity issue in a curve? why is a square relationship not significant? why does a standardised independent variable squared how does multicollinearity change after mean centered is the independent variable squared in a curvilinear relationship what does the squared independent variable do if it is positive is mean centering significant how to find u shaped relationship in linear regression why is it important to square the independent variable after mean centering? which of the following is true about the inverted u shaped relationship between a normal independent and an independent variable? can you prove the inverted relationship when only the independent variable is significant how can u shaped relationship be determined? do you have to square an independent variable for multicollinearity to be considered a normal independent? when does independent variable squared become significant how to calculate multicollinear relationship with independent variable
