As, we need to have a linear relationship between the variables to comprehend their relationship better, we need to transform non-linear relationships to linear ones. But I don’t seem to understand how this can be done. Can someone explain this with an example?
Suppose we see a curvilinear relationship between two variables using scatter plot, how can we get a linear relationship out of it? Does log transformation works in most of the situations? Do we need to try out all the transformations?
What would be a good way to tackle this issue while solving problems?
