Figure 3-1. A Proposed Model

 Maximum likelihood generates an estimated chi-square statistic and as such

provides a probability value indicative of the overall fit of the model since the

distribution of chi-square value is known (Bollen, 1989). The value of the chi-square

statistic, in relation to the model's degrees of freedom, determines whether the fitted

residuals, resulting from I 1(9), deviate from the population values of zero. The

differences between the corresponding elements of the implied covariance matrix

(theory) and the observed covariance matrix (reality) consist of the matrix of residuals.
