gigFit problems
...Debian.
Although I got a good fit for the density function with the GIG equation
in another curve fitting program, I would really like to use R's tools
for confidence intervals and manipulations; but the problems below make
me uneasy.
Problem one (from examples with parameter change):
Code:
paramStart.X2002<-c(2.044, .622, 2)
param<-paramStart.X2002
dataVector <- rgig(500, param = param)
gigFit(dataVector)
Result
Data: dataVector
Parameter estimates:
chi psi lambda
0.007543 0.722962 2.535284
Likelihood: -644.6349
Method: Nelder-Mead
