addreg 3.0

• method option added: fit using combinatorial EM or single parameter expanded EM algorithm
• accelerate option added: use turboEM to allow acceleration of EM algorithm
• Corrected an error in the calculation of deviance residuals for family = negbin1
• Corrected an error in the calculation of null deviance for family = negbin1
• (Minor change) Change iter to return a vector of two values

addreg 2.0

• Added additive negative binomial regression (family = negbin1)
• (Minor change) Removed bin.identity link function; avoided CRAN error in a simpler way
• (Minor change) Documentation changes, including updated references

addreg 1.2

• Introduced bin.identity link function: identical to the standard identity link, but does not cause an error when used with the binomial family.
• (Minor change) Corrections to avoid codetools errors.

addreg 1.1

• The object returned by nnpois() now includes component standard.
• (Minor change) Various very minor corrections.

addreg 1.0

• Added na.action argument to addreg() and addreg.smooth()
