Thus, the same default formula processing is applied to
zero-inflated and hurdle models.

added (which in particular explains the ideas behind
zeroinfl() and hurdle()).
* correcting/improving documentation of ideal re identification and the normalize option
* added absentee ballot data from Orley Ashenfelter, used in
BASS

binomial(link = linkstr) instead

* finally changed ideal model to have a negative intercept; required changes to
updatex.c, updatey.c, and xreg.c
0.72 * fixed error in bioChemists data found by Bettina Gr?n
, variable kids5 was off by 1 unit, now runs
from min of zero (no kids).
0.71 * fixed bug in betaHPD discovered by John Bullock
0.70 * completely rewritten version of hurdle() and zeroinfl():
- new formula interface of type y ~ x | z where y ~ x
specifies the count model and z the inflation/hurdle
regressors.

"glm" objects
- extended/enhanced extractor functions

Lewis
* cosmetic changes to print.summary.rollcall
* fixed errors caused by removing sysdata.rda; now utility

via data() in functions inside readKH subfunctions; again,
Jeff Lewis reported error testing readKH function.
0.60 * added postProcess
* added jitter to plot.predict.ideal
