Changes in version 2.0 (February 2019)

o Many changes motivated by submitted paper: Andrade, BB; Matsushita, RY; Oliveira, SB (submitted) Analyzing Count Data with the Touchard Model. \emph{Annals of Applied Stats}. o toureg() extensively modified: regression with log(mu) included; methods 'qp1', 'qp2' and 'glm' added. o predict.toureg() and plot.toureg() modified and no longer compatible with previous version. o hatvalues() and cooks.distance() replaced by hvalues() and cooks.dist(). o NEWS added.

Changes in version 1.0 (August 2018)

o The 'touchard' package was first published on CRAN. o rtouch() modified so that numerical arguments other than 'n' are recycled to the length of the result in accordance with other rng functions in R. o toureg() added: regression with log(lambda) = linear predictor.
o bug fixed in ptouch() when 'log=TRUE'. o tau() added (formerly invisible) allowing computation by truncation of series and (added) by recursion (stopping at given relative error). o Datasets Accidents and Crabs added.

Changes in versions 0.1.0, 0.1.1, 0.2.0 (2018)
