Adding the Hessian to ivplm.
Fixing bug with the LR test in "hetprob()"
New urls in Description.
New README.
New methods for effect.
Improved documentation.
AIC and BIC for different classes are dropped. We just need "logLik()".
Changing the behavior of set.seed as a good practice.
Fixing bug with mtable.
Add hetprob function to estimate heterokedastic binary models.
Add ivplm function to estimatate instrumental variables probit model by Maximum Likelihood.
Fix minor bug in the model.frame.rFormula function with new update of plm.
Slightly improved documentation.
Fixing errors and warnings
Including CITATION
fixed minor bug in the model.frame.rFormula function when the id variable is specified using pdata.frame function
the package not longer includes a vignette. The documentation can be dowloaded at http://msarrias.weebly.com/rchoice-package-in-r.html
fix some notes regarding to the AIC and BIC methods
statistic in summary is now labeled as z-value instead of t-value
cov.Rchoice, cor.Rchoice and se.cov.Rchoice functions are now deprecated. All these functions are now available in the generic function vcov
slightly improved documentation
panel data or longitudinal data is now allow
added the function se.cov.Rchoice to compute the standard error of the variance-covariance matrix of random parameters
more flexibility to model hirarchical variables. The argument mvar can be used to choose which variables enter in the mean of the random parameters.
added the Johnson's Sb function for random parameters.
added the rFormula and related functions
initial values for standard deviation of random parameters are set to 0.1. Previously was 0. The argument init.ran can be used to set the initial values. For example init.ran = 0 will set all the initial values for the standard deviation paramters at 0
slightly improved documentation
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
