df in ANOVA-type test within the npaLD package

I used a non-parametric test for my data, called ANOVA-type test, using the npaLD package in R.
Degrees of freedom for the denominator in defined to infinity.
May someone please help me understand (I'm not a big expert in statistics) the meaning of infinite df?
Thank you very much!


according to the npaLD package documentation, df should correspond to the degrees of freedom of some Fisher-Distribution. Which one exactly depends on the function you used. You can find more information in the package documentation.

nparLD: Nonparametric Analysis of Longitudinal Data in Factorial Experiments (r-project.org)

In terms of interpretation, infinite degrees of freedom suggest to me that something went wrong in your analysis. Maybe you can post more details on that?
