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 ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
