Logistic regression is a statistical method used for binary classification problems, where the outcome is one of two possible categories. It models the relationship between a dependent binary variable and one or more independent variables by estimating probabilities using a logistic (sigmoid) function. The output is a probability value that is mapped to one of the two possible classes using a threshold, typically 0.5.
In logistic regression, the model predicts the log-odds of the dependent variable being in a particular category. The log-odds are a linear combination of the independent variables.
Where:
– \( p \) is the probability of the dependent variable being 1.
– \( \beta_0 \) is the intercept.
– \( \beta_1, \beta_2, \ldots, \beta_n \) are the coefficients of the independent variables \( X_1, X_2, \ldots, X_n \).
Logistic regression is widely used in fields such as medicine, finance, and social sciences for tasks like disease prediction, credit scoring, and survey analysis.

Logistic regression is a statistical model used to analyze the relationship between a dependent variable (binary outcome) with one or more independent variables. It is commonly used for classification of problems where the dependent variable is categorical.
Logistic regression estimates the probability that a given input belongs to a certain category by applying a logistic function to the linear combination of the independent variables. It is widely used in various fields such as machine learning, statistics, and social sciences for modeling and predicting categorical outcomes.
