However, this is not strictly valid because linear regression is based on a The regression equation for y on x is: y = bx + a where b is the slope and a is the It allows us to compute fitted values of y based on values of x. ˆy = a+ bx. Problem . Apply the simple linear regression model for the data set faithful, and estimate A residual is the difference between an observed dependent value and one predicted from the regression equation. Assumptions for regression. Assumptions . The Least-Squares Regression Line (shortcut equations).

0.95 in the equation is the slope of the linear regression which defines how much of the variable is the dependent variable on the independent variable. However, this is not strictly valid because linear regression is based on a The regression equation for y on x is: y = bx + a where b is the slope and a is the It allows us to compute fitted values of y based on values of x. ˆy = a+ bx.

The formula for the coefficient or slope in simple linear regression is: The formula for the intercept ( b 0 ) is: In matrix terms, the formula that calculates the vector of coefficients in multiple regression is: Linear regression is the technique for estimating how one variable of interest (the dependent variable) is affected by changes in another variable (the independent variable). If it is one independent variable, it is called as simple linear regression. When there are more than one independent variable it is called as multiple linear regression.

Our sample size is too small to really fit anything beyond a linear model. But we did so anyway -just curiosity.

Coefficient of Determination = {Correlation Coefficient (x,y)}2! Shortcut formula for SSE: The aim of linear regression is to model a continuous variable Y as a mathematical function of one or more X variable (s), so that we can use this regression model to predict the Y when only the X is known. This mathematical equation can be generalized as follows: Y = β1 + β2X + ϵ where, β1 is the intercept and β2 is the slope.
