Collinearity was not found in the variables included in the model, verified by variance inflation factor.
In multiple linear and logistical regressions, collinerarity was verified by variance inflation factor (VIF > 5), tolerance (> 30) indices and correlation matrices respectively.
We select the test according to the normality from the samples: for normal samples, we verify the variances of the samples, and perform the Analysis of Variance (ANOVA) and for non-normal samples, the Kruskal-Wallis test.
The results preliminarily verified that the variance WIE is able to measure the complex degree of SAR images.
This can easily be verified by the variance of the alignment depth or by viewing the distribution of the sampled depth directly.
The cumulative hazard functions for each covariable were computed to assess proportionality, and colinearity was verified by calculating variance inflation factors.
This was verified with the variance inflation factor (VIF), based on the guideline that this statistic should not be greater than 3.3 for any formative indicator [ 71].d As shown in Table 5, this condition held for all six indicators.
Two-way ANOVA (homogenous variance verified by Levene test for all parameters except Cds1 and Acsl1) was used to study the global effect of sex and treatment, followed by Student-Newman-Keuls post hoc test to determine individual differences.
Regional differences between groups in mRNA expression and PMI were assessed by two-way analysis of variance (ANOVA) for repeated measures after the logarithmic transformation to ensure normality of distributions and homogeneity of variances (verified by Kolmogorov-Smirnov and Levene tests, respectively).
Normal distribution and homogeneity of variance were verified using a Normality test and a F-test for variance.
Continuous variables with normal distribution were compared between the treatment group and the placebo group by two-way analysis of variance (ANOVA) taking into account stratification by GA if homogeneity of variance was verified, and by Student's t-test if ANOVA failed to show any effect of GA.
