3.2.4 Regression analysis.Testing theory model through Multiple Linear Regression analysis:After extracting factors obtained from Exploratory Factor Analysis, then MultipleLinear Regression analysis is reasonably used. Multiple linear Regression analysis is astatistical approach used to analyze the relationship between a dependent variable andindependent variables. The purpose of using the Multiple Linear Regression method is todescribe the relationship and simultaneously help us predict the extent of dependent whenwe foresee the value of independent variables. When running the Multiple linearRegression model, we should pay intention some parameters, including:38Beta coefficient: Standardize regression coefficients allow researchers to comparedirectly between coefficients based on the interpreting relationship of the coefficientswith the dependent variable.Coefficient of determination R2: Evaluate the changing part of the independentvariable interpreted independent variables or predictor variable. The R2 fluctuates from 0to 1.Adjusted coefficient R2: Since Coefficient of determination R2 is demonstrated to bea function that can not be decreased along with independent variables mounted into themodel. The more independent variables mount into model, the more the value of R2increases. However, the equation containing many variables is not always a suitableequation, which is demonstrated. By comparing the model whose adjusted coefficient R2is greater other models whose adjusted coefficient R2 will explain satisfaction labors
