  Partial regression slope coefficients: the expected change in Y with a one-unit change in X1. That is, when all other independent variables are held constant. In multiple regression, we follow our standard 11 steps to happiness, and next class we’ll get into step six, checking for multicollinearity.

• Why do coefficients change in multiple regression?

  The strength of prediction from a multiple regression equation is nicely measured by the square of the multiple correlation coefficient, R2 . In the case of only two predictors, R2 can be found by using the formula (7) In our example, we find

  Interpreting the Correlation Coefficient R. Customarily, the degree to which two or more predictors (independent or X variables) are related to the dependent (Y) variable is expressed in the correlation coefficient R, which is the square root of R-square. In multiple regression, R can assume values between 0 and 1.

  The multiple regression model fitting process takes such data and estimates the regression coefficients (, and ) that yield the plane that has best fit amongst all planes. Model assumptions. The assumptions build on those of simple linear regression: Ratio of cases to explanatory variables. Invariably this relates to research design.

  The coefficient of multiple determination measures the proportionate reduction in the variation of Y achieved by the introduction of the entire set of X variables. ... (the regression coefficient for X1 is the same for both model (1) and (2). The same holds for regression coefficient for X2.

Interpretation of multiple regression coefficient on a variable depends on what other explanatory variables are in the model.
