The transformations you have seen in the past can also be used to move and resize graphs of functions. We will be examining the following changes to f (x): - f (x), f (-x), f (x) + k, f (x + k), kf (x), f (kx) reflections translations dilations. Reflections of Functions: -f (x) and f (-x)
A logarithmic transformation can be applied to highly skewed variables, while count variables can be transformed using a square root transformation. Overall, the violation of the homoscedasticity assumption must be quite severe in order to present a major problem given the robust nature of OLS regression.
