This page lists down the** practice tests** / **interview questions and answers** for **Logistic** **regression** in** machine learning**. Those wanting to test their machine learning knowledge in relation with logistic regression would find these practice tests very useful. The goal for these **practice** **tests** is to help you check your knowledge in logistic regression machine learning models from time-to-time. More importantly, when you are preparing for **interviews**, these **practice tests** are intended to be handy enough. Those going for **freshers** / **intern** interviews in the area of machine learning would also find these practice tests / interview questions to be very helpful.

This test primarily focus on following concepts related with logistic regression:

- Introduction to logistic regression
- Logistic regression examples
- Types of logistic regression (Binomial, Multinomial, Ordinal)
- Link function
- Evaluation of logistic regression

Other tests in this series includes some of the following:

### Logistic Regression Concepts (Brushing up)

- Logistic regression is used to estimate / predict the discrete valued output such as success or failure, 0 or 1 etc.
- Examples of problems where logistic regression can be used is whether a person is suffering from a specific disease or not; Or, a person is suffering from disease A, disease B or disease C
- Logistic regression can be types such as binomial, multinomial and ordinal
- Logistic regression is used to estimate the likelihood of outcome dependent variable instead of actual value as like linear regression model
- Logistic regression model is evaluated using concepts such as AIC, Deviance calculations (Null and Residual/ Model deviance) ROC curve etc.
