Shapiro wilk test normality p value
Webb12 apr. 2024 · If the p-value is less than a significance level (usually 0.05), the residuals are likely to deviate from normality. Test for homoscedasticity To test for homoscedasticity, you can use graphical ... The null-hypothesis of this test is that the population is normally distributed. Thus, if the p value is less than the chosen alpha level, then the null hypothesis is rejected and there is evidence that the data tested are not normally distributed. On the other hand, if the p value is greater than the chosen alpha level, then the null … Visa mer The Shapiro–Wilk test is a test of normality.
