To conduct a multiple linear regression analysis, the variables are inserted into the model by the Enter method. Auditing standards is the standard built in test method F statistic values and determine the probability of the F statistic values, testing the degree of fit between the model and the overall through the coefficient of determination R2. The diagnostic tool helps to detect the existence of most online communities in data rate plus do online estimate for parameters degradation is: magnification coefficient of variance (Variance inflation factor-VIF). The rule is when the VIF exceeds 10, which is the hallmark of most online communities.
