Hey everyone. I have a dataset comprising of patient data and their biochemical test results. I have numerical variables and categorical variables like YES/No. I want to run numerical tests like Annova and others into this data set. But I also have categorical variables with values like ( Mother, father, both and none). I have used boolean values to imply the Yes/No values but I don't know what to do with categorical variables with more than binary values and more than 2 values. And I am confused on how to run numerical tests for those? Please help me out.
