CHANGES IN VERSION 1.1-4

NEW FEATURES

• Fixed compatibility with mlogit >= 2.0-0 and dfidx-based mlogit.data objects. This restores latent-class model estimation with recent versions of mlogit, including examples using the Fishing and Electricity data sets.

• Fixed mixed-mixed logit models when some coefficients are fixed and others are random. Previously, model = "mm" could fail when ranp did not include all variables in the utility specification.

• For mixed-mixed logit models, 'Qir' now stores both prior class probabilities ('wnq') and posterior class probabilities ('qir').

CHANGES IN VERSION 1.1-3.3

NEW FEATURES

• Fixed bug with model frame.

• Fixed id issue.

CHANGES IN VERSION 1.1-3.2

NEW FEATURES

• More arguments are passed on to maxLik.

• Fixed bug with weights.

• Correcting dependency with mlogit

CHANGES IN VERSION 1.1-3

NEW FEATURES

• CITATION in now included.

CHANGES IN VERSION 1.1-2

FIXED BUGS

• The predicted probabilities for each individual in each class are now accesibles through the element Wnq.

CHANGES IN VERSION 1.1.1

NEW FEATURES

• Fixed bug when the data of mlogit class has an id.var, but the model is estimated as a cross-section. Thanks to Maryam Zabihi (maryam.zabihi@mavs.uta.edu) for pointing this out.

CHANGES IN VERSION 1.1

FIXED BUGS

• Fixed bug in the conditional means when computing WTP in the LC model.

• When start is not null, the log and Sb transformations are not applied.

• z-statistics are now correctly labeled.

• Fixed bug of initial values when a parameter is distributed as Sb.

NEW FEATURES

• The documentation can be dowloaded at http://msarrias.weebly.com/rchoice-package-in-r.html.

• cov.gmnl, cor.gmnl and se.cov.gmnl functions are now deprecated. All these functions are now available in the generic function vcov.

• Added individual-specific estimates for the Mixed-Mixed Model.

• Now constraints argument can be passed to maxLik using gmnl.

• Slightly improved documentation
