What is multinomial logistic regression?

Multinomial logistic regression is a statistical method used to model the relationship between one or more independent variables and a categorical dependent variable with more than two unordered categories. It is an extension of binary logistic regression to situations where the outcome variable has multiple categories that are not ordered. In multinomial logistic regression, the dependent variable is categorical and nominal, meaning the categories have no natural ordering. Examples of such variables include types of diseases (e.g., cancer types), political…

What is ordinal logistic regression?

Ordinal logistic regression is a statistical method used to model the relationship between one or more independent variables and an ordinal dependent variable. It is an extension of binary logistic regression to situations where the outcome variable has more than two ordered categories but maintains the ordinal nature of the categories. In ordinal logistic regression, the dependent variable is categorical and ordinal, meaning it has a natural ordering but the intervals between categories may not be equal. For example, Likert…

What is logistic regression?

Logistic regression is a statistical method used for binary classification, a type of supervised learning.

For example, it can be used to predict whether an email is spam (1) or not spam (0), whether a student will pass (1) or fail (0) an exam, etc. Despite its name, logistic regression is used for classification,…
