What type of data would you use with logistic regression?

Logistic Regression is used when the dependent variable(target) is categorical. For example, To predict whether an email is spam (1) or (0) Whether the tumor is malignant (1) or not (0)

Can logistic regression use nominal variables?

As with other types of regression, multinomial logistic regression can have nominal and/or continuous independent variables and can have interactions between independent variables to predict the dependent variable.

Is logistic regression linear or nonlinear?

Logistic regression is known and used as a linear class i fier. It is used to come up with a hyper plane in feature space to separate observations that belong to a class from all the other observations that do not belong to that class. The decision boundary is thus linear .

Can we use logistic regression for regression problem?

Since both are part of a supervised model so they make use of labeled data for making predictions. Linear regression is used for regression or to predict continuous values whereas logistic regression can be used both in classification and regression problems but it is widely used as a classification algorithm.

Can logistic regression be used for prediction?

Logistic regression is used to predict the class (or category) of individuals based on one or multiple predictor variables (x). It is used to model a binary outcome, that is a variable, which can have only two possible values: 0 or 1, yes or no, diseased or non-diseased.

Is it better to have continuous predictors in logistic regression?

This can cut two ways, but mostly one. In logistic regression, as with any flavour of regression, it is fine, indeed usually better, to have continuous predictors. Given a choice between a continuous variable as a predictor and categorising a continuous variable for predictors, the first is usually to be preferred.

What is logistic regression analysis in research?

Logistic regression analysis is a statistical technique to evaluate the relationship between various predictor variables (either categorical or continuous) and an outcome which is binary (dichotomous). In this article, we discuss logistic regression analysis and the limitations of this technique.

What is an independent variable in logistic regression?

Independent variables are those variables or factors which may influence the outcome (or dependent variable). So: Logistic regression is the correct type of analysis to use when you’re working with binary data.

What is binary logistic regression with example?

Binary logistic regression is the statistical technique used to predict the relationship between the dependent variable (Y) and the independent variable (X), where the dependent variable is binary in nature. For example, the output can be Success/Failure, 0/1, True/False, or Yes/No.
