Hey,
I don't really get the output of the performed Levene's test.
So in short.
two data sets, one with 75 elements, one with 283.
And I want to check whether they have the same variance.
I did a LeveneTest
And this is the output:
Levene's Test for Homogeneity of Variance (center = median)
I don't really get the output of the performed Levene's test.
One answer would be to read John Fox's rather good book, for which car is the
corresponding R package.
Another is to look up leven'es test; a reasonably authoritative web reference

Sorry i'm not the biggest statician, but I still find the output write
out not the clearest of all. Anyway, that is probably a personal
problem. :-)
Just one question.
Hello,
Just to add to the last post, you can try to get that p-value using what
that output gives you:
df1 - 1
df2 - 356
F_stat - 10.948
pf(F_stat, df1, df2, lower.tail = FALSE) # same value
Hope this helps,
