Subject: Testing a timeseries for heteroscedastic (lmtest)
Hello,
my intention is to test a given timeseries (vector) for heteroscedastic.
Now I found the gqtest/bptest/hmctest in the lmtest package but a
"formula" as argument is needed.
What is meant by formula and how du I interpret the timeseries as
formula.
Thanks in advance
Simon
