np_anova
performs a nonparametric ANOVA.
np_anova(ordered_vars, predictor_vars, uvw)
ordered_vars |
a data frame for the ordered variables being assessed. |
predictor_vars |
a data frame for the un-ordered variables being assessed. |
uvw |
the degree being assessed. This should be a vector with length
equal the number of elements in the |
Nonparametric ANOVA is a methodology that is applicable where one as an ordered response variable as well as both ordered response and predictor variables.
Where there is only one ordered variable, the function returns a type III
ANOVA table to test for differences of order uvw
across the levels of
the predictor_vars
.
Where there is more than one ordered variable, the function returns a type
III ANOVA table to test for differences in generalised correlations of order
uvw
across the levels of the predictor_vars
