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'.
