Der Levene-Test ist eine Alternative zum weniger empfindlichen Barlett-Test. Die R-Sprache hat eine MethodeleveneTest(), um den Levene-Test durchzuführen; Diese Methode stammt aus dem Pflegepaket der Sprache R. Zuerst müssen wir das Autopaket installieren, falls es noch nicht installiert is...

The test-retest reliability for the determination of vibration perception thresholds (VPTs) expressed as SI-indices was also good to excellent for digit 2, left hand as well as for digit 5, bilaterally (LOA 96–100%; ICC ≥ 0.84; r ≥0.85;), and lower (LOA 100%; ICC = 0.59; r = ...
A homocedasticidade foi verificada pelo teste de Levene (p = 1.000). A fidedignidade interavaliadores (avaliador vs. avaliador, para um mesmo equipamento) considerou separadamente as medidas feitas entre cronômetros e, posteriormente, apenas as medidas das análises de vídeo (correlação...
To test for equality of variances in two independent random samples from univariate normal populations, popular choices would be the two sample F test and Levene's test. The latter is a nonparametric test while the former is parametric: it is the likelihood ratio test, and also a Wald test....

(40% remaining consecutive patients) datasets. Normal distribution of input features was assessed by means of the Kolmogorov–Smirnov’s test, whereas the Levene’s test was used to assess homogeneity of variances. Accordingly, the non-parametric Mann-Whitney U test was used to assess differences ...
Before running the MANOVA analysis, the figures of Kurtosis and Skewness showed that the assumption of univariate normality was satisfied (see Table 8 inAppendix E), and the results of Levene's test of homogeneity of variances indicated that the assumption of homogeneity of variances was also sati...
