Fitted values regression
WebFitting the Multiple Linear Regression Model Recall that the method of least squares is used to find the best-fitting line for the observed data. The estimated least squares regression equation has the minimum sum of squared errors, or deviations, between the fitted line and the observations. WebTo get the fitted values we want to apply the inverse of the link function to those values. fitted () does that for us, and we can get the correct values using predict () as well: R> predict (md2, type = "response") 1 2 3 4 5 6 0.4208590 0.4208590 0.4193888 0.7274819 0.4308001 0.5806112
