However, in most problems, no single regression model is best in terms of the various evaluation criteria that have been proposed A great deal of judgment and experience with the system being modeled is usually necessary to select an appropriate set of regressor variables for a regression equation No single algorithm will always produce a good solution to the variable selection problem Most of the currently available procedures are search techniques, and to perform satisfactorily, they require interaction with judgment by the analyst We now briefly discuss some of the more popular variable selection techniques We assume that there are K candidate regressors, x1, x2, p , xK, and a single response variable y All models will include an intercept term 0, so the model with all variables included would have K 1 terms.

The attributes of the Web server control are properties of that control, and may or may not be attributes in the generated HTML.

Furthermore, the functional form of each candidate variable (for example, x1 1 x, x2 ln x, etc) is correct All Possible Regressions This approach requires that the analyst fit all the regression equations involving one candidate variable, all regression equations involving two candidate variables, and so on Then these equations are evaluated according to some suitable criteria to select the best regression model If there are K candidate regressors, there are 2K total equations to be examined For example, if K 4, there are 24 16 possible regression equations; while if K 10, there are 210 1024 possible regression equations Hence, the number of equations to be examined increases rapidly as the number of candidate variables increases.

However, there are some very efficient computing algorithms for all possible regressions available and they are widely implemented in statistical software, so it is a very practical procedure unless the number of candidate regressors is fairly large Several criteria may be used for evaluating and comparing the different regression models obtained A commonly used criterion is based on the value of R2 or the value of the 2 adjusted R2, Radj Basically, the analyst continues to increase the number of variables in the 2 2 model until the increase in R2 or the adjusted Radj is small Often, we will find that the Radj will stabilize and actually begin to decrease as the number of variables in the model increases 2 Usually, the model that maximizes Radj is considered to be a good candidate for the best re2 gression equation.

Because we can write Radj 1 {MSE [SSE (n 1)]} and SSE (n 1) 2 is a constant, the model that maximizes the Radj value also minimizes the mean square error, so this is a very attractive criterion Another criterion used to evaluate regression models is the Cp statistic, which is a measure of the total mean square error for the regression model We define the total standardized mean square error for the regression model as 1.

Consider using HTML server controls when:

We use the mean square error from the full K 1 term model as an estimate of 2; that is, 2 MSE 1K 12. Then an estimator of p is [see Montgomery, Peck, and Vining (2001) or Myers (1990) for the details]:
