WebY2 has only three categories (0/1/2) so that I doubt we can treat it as a continuous independent variable, and I wonder if it is appropriate to generate two dummy variables corresponding to Y2=1 and Y2=2 to replace Y2 in the first equation (Y1 ON Y2 X1 X2). Alternatively, can I do this in the following way?

But this time let’s examine the impact of job prestige level (a continuous variable) and gender (a categorical, dummy coded variable) as our two predictors. Here, gender is called “male” and is coded 1 for males and 0 for females.

WebSecond, converting categorical variables to values between 0 and n-1 and then treating them as continuous variables makes no sense. Third, one-hot categorical variables are so non-Gaussian, that treating them as Gaussian (which GaussianNB assumes) does not, in my experience, produce good results. – Him.
