Dear R users,
I'm trying to fit stable distribution and hyperbolic distribution to my data
using stableFit(), and hypFit() of fBasics.
However, there are some problems
This is the result
======================================
> stableFit(lm, alpha = 1, beta = 0, gamma = 1, delta = 0, doplot = TRUE, trace
> = FALSE, title = NULL, description = NULL)
Title:
Stable Parameter Estimation
Call:
.qStableFit(x = x, doplot = doplot, title = title, description = description)
Model:
Student-t Distribution
Estimated Parameter(s):
alpha beta gamma delta
NA NA NA NA
======================================
first, this is stable distribution, but in "Model", it's always Student-t
Distribution.
Second, everytime I run stableFit(), the result of Estimated Parameter(s) is
NA. I can't really find what's wrong in my code.
In the case of hyperbolic distribution, this is the result
======================================
Model:
Hyperbolic Distribution
Estimated Parameter(s):
alpha beta delta mu
63.201132 1.991194 11.165716 2.921906
There were 41 warnings (use warnings() to see them)
Warning messages:
1: NA/Inf replaced by maximum positive value
2: NA/Inf replaced by maximum positive value
...........................................
======================================
First, I don't what the warning messages mean and why they appeared.
Many thanks in advance
