=0) or 1.5 (y>0) when not explictly specified
- Fixed an error that reported the wrong mle of phi when the mle
occured at an endpoint of the given xi values.
26 August 2010: tweedie 2.0.5
- Change to dtweedie.inversion to ensure density=0 is returned
when y<0 (12)
- Change to tweedie.profile to fix a problem that p=1 returned an error
- Changed so that tweedie.profile works withg p/xi = 0 when add0=TRUE (default is FALSE)
- Fixed some minor outputting messages (when verbose==2)
- Location of CITATION file moved to correct location
12 July 2010: tweedie 2.0.4
- Minor edits
18 December 2009: tweedie 2.0.3
- Changed default p.vec: There were too many values
- Added the facility to refer to p as xi in line with GLMs text
17 November 2009: tweedie 2.0.1
- Changed the default p.vec when 1

)
tweedie 1.6.7
- Correct error in rtweedie when power=1 and phi\ne 1
(Thanks to Frederic Gosselin )
tweedie 1.6.6
- Corrected specification of GPL; no changes to functionality, code or documentation
tweedie 1.6.5
- In dtweedie, added power==3 (inverse Gaussian) as a special case
- Minor change in documentation
tweedie 1.6.4
- Added data, weights, and offset input arguments
- Fixed a bug where "=>" was used rather than ">="
tweedie 1.6.3
- Fixed a bug in tweedie.profile: exact zeros still allowed p=2 (but not p>2)
tweedie 1.6.2
- Fixed a bug in ptweedie.inversion where variable cdf was undefined
- Fixed a bug in qtweedie where any(power)<1 should have been any(power<1)
tweedie 1.6.1
- Fixed error in tweedie.f (twice) where a float was used in a do-loop
tweedie 1.6
- Fixed a bug in ptweedie: It now returns 0 when y<0 (rather than reporting an error)
- Fixed a bug in ptweedie.inversion: y.len was undefined
- Fixed a bug in dwteedie.inversion: if( any(phi<0) ) written as if (any(phi) <0 )
tweedie 1.5.3:
- Built for R version 2.6.0
- Changed the tweedie.plot to produce no default x and y labels
tweedie 1.5.2:
- Built for R version 2.5.1
- Removed the inversion computation from the example for dtweedie;
it was very slow and hence caused problems
tweedie 1.5.1:
- Built for R version 2.5.0
- Fixed citation details
- Added note in dtweedie help page indicating where the methods
are defined (Dunn and Smyth, 2007).
- Added tweedie-package.Rd
- Fixed a small bug in dtweedie.inversion (replaced p with power)
02 May 2007: tweedie 1.5
- Built for R version 2.5
- Made change to use of pmatch in function tweedie
- Swapped the order of methods 1 and 2 in the call of
tweedie.inversion to make consistent with a change
in the associated paper Dunn and Smyth.
- Fixed an uninitialized variable error in the FORTRAN code
which sometimes caused the inversion procedure to fail.
- Other minor changes (fixing spelling errors, updated
Dunn and Smyth reference; etc.)
04 December 2006: tweedie 1.4
- Some very minor changes (some cosmetic) in the code
- Made the code more robust, exiting gracefully when Inf and NA appear
in the computed log-likelihood
- Slightly changed the output plot in tweedie.profile, to reflect
that some value of p.vec may not have a corresponding likelihood
computed accurately (or, indeed, at all)
- Added new function tweedie.plot to make it easier to plot Tweedie
densities
tweedie 1.02
- Built for R version 2.0.0
- Major fix: The mle estimate of phi was incorrect in tweedie.profile
(thanks Sarah Lennox, QDPI&F)
- Some better warnings in tweedie.profile
- tweedie.profile now allows the actual computed points to
be added to the plot using the do.points option (default
is TRUE)
- The tweedie.profile function now smooth and computes
confidence intervals even when the computed likelihood
values contain Infs or NAs.
tweedie 1.01
- Built for R version 1.9
- fixed a bug in rtweedie: it failed for p=2 (thanks
Sarah Lennox, QDPI&F)
- fixed a bug in qtweedie: it failed in some cases
(thanks Gordon Smyth, WEHI)
- added a proper .First.lib function (!) (thanks to
James Wettenhall and Gordon Smyth, WEHI)
- other minor bugs fixed
- the tweedie family function removed, and package
made dependent on the statmod package
- updated for R version 1.9
tweedie 1.0
- Built for R version 1.7
