Global goodness-of-fit
WebGoodness-of-fit is a statistical method for assessing how well a sample of data matches a given distribution as its population. In other words, the technique is used for checking the accordance between observed and expected data. The test types include the Chi-Square test, Kolmogorov-Smirnov (K-S) test, the Anderson-Darling (A-D) test, and ... WebThe goodness of fit (GoF) has been developed as an overall measure of model fit for PLS-SEM. However, as the GoF cannot reliably distinguish valid from invalid models and …
