    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'.
