Test Normality
...Night
I made different test to check normality and multinormality in my dataset,
but I don´t know which test is better.
To verify univariate normality I checked: shapiro.test, cvm.test, ad.test,
lillie.test, sf.test or jaque.bera.test and
To verify multivariate normal distribution I use mardia, mvShapiro.Test,
mvsf, mshapiro.test, mvnorm.e.
I have a dataset with almost 1000 data and 9 variables, in both cases the
result is non-normality. For this reason, I transformed data with bcPower
function and I want to check normality again.
I really appreciate your help.
Thanks.
