A Latent Variable Model for Mixed Continuous and Ordinal
Responses
Ehsan Bahrami Samani and Nourallah Tazikeh Miyandarreh
A model for mixed ordinal and continuous responses is
presented where the heteroscedasticity of the variance of the
continuous response is also modeled. In this model ordinal
response can be dependent on the continuous response. The aim
is to use an approach similar to that of Heckman (1978) for the
joint modelling of the ordinal and continuous responses. With
this model, the dependence between responses can be taken into
account by the correlation between errors in the models for
continuous and ordinal responses

This package provides several LVQ algorithms along with
different usage methods and output visualization.

The manual approach of Litchfield and Wilcoxon (1949)
<http://jpet.aspetjournals.org/content/96/2/99.abstract>
for evaluating dose-effect experiments
is automated so that the computer can do the work.

Provides a flexible and easy-to use interface for the soil vegetation
atmosphere transport (SVAT) model LWF-BROOK90 as described in Hammel & Kennel
(2001, ISBN:978-3-933506-16-0) and Federer et al. (2003) <doi:10.1175/1525-7541(2003)004%3C1276:SOAETS%3E2.0.CO;2>.
The model simulates daily transpiration, interception, soil and snow evaporation,
streamflow and soil water fluxes through a soil profile covered with vegetation.
A set of high-level functions for model set up, execution and parallelization
provides easy access to plot-level SVAT simulations, as well as multi-run and
large-scale applications.
