- n. A property of a set of random variables where each variable has the same finite variance.
Sorry, no etymologies found.
Parker considered simple autocorrelation, but the this sort of data also exhibits homoscedasticity, as well as spatial and long-term-temporal correlations that likely need to be addressed, too.
For all that, the normality of the residues was tested using the Shapiro test and the homoscedasticity (homogeneity of the variances) using the Bartlett test.
Hartley's Fmax test was used to determine variance homoscedasticity between data sets.
And, if homoscedasticity is suddenly so important, let’s hear an a priori declaration without peeking at the results from the tree ring experts of what the cut-off is that disqualifies a series.
(one-way ANOVA under homoscedasticity hypothesis and Student t tests on contrasts) were employed.
