hi, i tried to fit the GED for my sample. when doing this without the package normalp i received a shape parameter p of about 0.5, whereas 'paramp' told me that p is 1 sharp. for a leptokurtic shape p should be in a range of 0<p<2. i don't understand why it isn't possible to implement the GED with a shape parameter less than 1. i'd like to create a q-q-plot with 'qqnormp' with p=0.5. what can i do? regards -- View this message in context: http://r.789695.n4.nabble.com/shape-parameter-in-normalp-tp4576043p4576043.html Sent from the R help mailing list archive at Nabble.com.
