Fitted line plot minitab

WebAfter fitting the initial model, if you determine that the model does not fit the data or that the residuals do not meet the model assumptions, consider transforming the X or Y variable using log base 10 (log10). Transforming the variables can improve the model fit. For example, in the original scatterplot, the simple regression line does not ...
