Can you do a linear regression with categorical variables?
It is possible to include categorical variables in linear regression models, although it is not as straightforward as including continuous variables. However, it is possible to make inferences about differences between groups, both in mean values of the outcome and the effect of other variables on the outcome.
How do you deal with categorical variables in linear regression?
Categorical variables require special attention in regression analysis because, unlike dichotomous or continuous variables, they cannot by entered into the regression equation just as they are. Instead, they need to be recoded into a series of variables which can then be entered into the regression model.
Which regression model is best for categorical data?
We might for example, investigate the relationship between a response variable, such as a person's weight, and other explanatory variables such as their height and gender. “Logistic regression and multinomial regression models are specifically designed for analysing binary and categorical response variables.”
Logistic regression describes the relationship between a set of independent variables and a categorical dependent variable.
