Before development of the MLR models, the underlying
assumption of homoscedasticity of variances must be tested. This
assumption simplifies mathematical and computational treatment
of the model. Violations in homoscedasticity may result in overestimating
the goodness of fit as measured by the Pearson coefficient.
Based on Bartlett's Test for Equality of Variances, the
probability associated with the Chi-squared statistic is equal to
0.8870. Hence, the associated probability for the Chi-squared test is
larger than 0.05 and the assumption of homoscedasticity was met
[56].
