the reader is not expected to know the central limit theorem or hypothesis testing process. In addition, the reader is NOT expected to be an expert in Microsoft Excel, R, Python, or any other software that may perform a regression analysis. ...
All statistical analysis software and applications (Microsoft Excel add-ins) generate tables of regression output values. These output values are segregated into three common tables: regression statistics table; ANOVA table; and regression coefficient table. The chapter addresses interpretation of the OLS...
As the Output seems to have a trend of a Normal curve, I will be testing it with apolynomial regression( for the nonlinearity of degree 6). We can also try to fit 3rd order polynomial, basically a sort of hyperparameter. I have used the Tableau analytical tool ...
6. Always ask “so what?”…The “so what” question is about moving beyond the internal validity of a finding to asking about its external usefulness. Good advice although I also run across the opposite problem frequently, thinking that a study done in 2001 doesn’t tell us anything about...
(Of course, there are linear, non-monotonic machine-learned response functions that can, for instance, be created by themulti-variate adaptive regression splinesapproach. These functions are not highlighted here because they tend to be less accurate predictors than purely nonlinear, non-monotonic func...
