Interpret each of the slope coefficients
WebThe next step is to interpret the intercept and each slope coefficient in the SRF. Generally speaking, we interpret a slope coefficient in a multivariate model by saying that a one unit increase in X_p is associated with a Beta hat p change in Y hat, holding the other independent variables constant. WebFeb 20, 2024 · measuring the distance of the observed y-values from the predicted y-values at each value of x; squaring each of these distances; calculating the mean of each of the squared distances. Linear regression fits a line to the data by finding the regression coefficient that results in the smallest MSE.
