What is the difference between Regression and Logistic Regression? Can you explain the Assumptions/Conditions?

Regression is used to model Interval target variables where as logistic regression is used to model Categorical varaibles.

the formula generally used: Y = m1x1+m2x2+m3x3+m4x4+c

Regression Assumptions: Input variables are linearly related to target variable and that input variables and residuals are normally distributed, and independent with a mean of 0 and constant variance.

Logistic Regression: There are no distributional requirements for inputs in Logistic regression

Y= 1

1 + e^-(m1x1+m2x2+m3x3+m4x4)
