Study Notes

Regression Analysis

The equation for simple linear regression is Y = mx + b, where m is the slope and b is the intercept.
A multiple regression model is a statistical model that predicts the value of a continuous outcome variable based on multiple predictor variables.
The coefficient 'm' in simple linear regression represents the change in the outcome variable for a one-unit change in the predictor variable, while holding all other variables constant.
In multiple regression, the coefficients represent the change in the outcome variable for a one-unit change in the corresponding predictor variable, while holding all other variables constant.
The goal of regression analysis is to establish a relationship between a dependent variable and one or more independent variables, and to predict the value of the dependent variable based on the independent variables.

Geography

Nepal is known as the 'land of mountains'.
