Non Linear Relationships

If the correlation coefficient and the scatter diagram do not indicate linear relationship, then the relationship may be nonlinear. Two such relationships are of peculiar interest

y = ab^x and y = ax^b      

Both of these can be decreased to linear model. Multiple or simple linear regression methods are then utilized to determine the values of the coefficients.
