Binary Logistic Regression
What is a binomial logistic regression?
Binomial logistic regression, predicts the probability that an observation falls into one of two categories of a dichotomous dependent variable based on one or more independent variables that can be either continuous or categorical.
What are the three types of logistic regression?
Three main types of logistic regression are:
- Binary Logistic Regression
- Multinomial Logistic Regression
- Ordinal Logistic Regression
What is the target of binary logistic regression?
Target variable has two possible outcomes such as Spam or Not Spam, Cancer or No Cancer, etc.
How are categorical independent variables used in binary logistic regression?
Categorical variables are typically encoded using the dummy variables before being included in the logistic regression model.
How multicollinearity used in logistic regression?
Multicollinearity among independent variables can lead to the unstable estimates in the logistic regression. The Regularization techniques such as the L1 or L2 regularization can be used to the mitigate multicollinearity.
What is odds ratio in logistic regression?
Odds ratio represents the change in the odds of the dependent variable being ‘1’ for the one-unit change in the independent variable.
What is goodness of fit of a logistic regression model?
Goodness of fit in the logistic regression can be assessed using the various metrics such as the Hosmer-Lemeshow test, deviance, AIC , BIC and ROC curve analysis.
Binary Logistic Regression
Binary logistic regression is a statistical method to model the relationship between the binary outcome variable and one or more predictor variables. It is a fundamental technique in statistics and data analysis with wide-ranging applications in various fields such as healthcare, finance, marketing and social sciences.
In this article, we will learn about binary logistic regression discussing its definition, importance, methodology, interpretation, practical applications, and others in detail.
