WebAug 15, 2024 · Gaussian Distribution: Logistic regression is a linear algorithm (with a non-linear transform on output). It does assume a linear relationship between the input variables with the output. Data transforms of your input variables that better expose this linear relationship can result in a more accurate model. WebA. To change which levels are used as the reference levels, you can simply re-order the levels of the factor variable (test1 in the prueba data frame) with the factor() function.B.
