Mathematics Behind Binary Logistic Regression
Binary logistic regression uses the logistic function known as the sigmoid curve to model the relationship between the independent variables and the probability of the binary outcome. The logistic function is defined as:

where,
- P(Y = 1∣X) is Probability of Outcome Variable
- Y is equal to 1 given Values of Independent Variables X
- e is Base of Natural Logarithm
- z is Linear Combination of Independent Variables and their Coefficients
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.
