Identification of cardinal dates in ecological time series

The package helps to identify cardinal dates (begin, time
of maximum, end of mass developments) in ecological time series
using fitted Weibull functions.

Cardiovascular Safety Exposure-Response Modeling in Early-Phase
Clinical Studies
Includes 100 mixed-effects model structures describing the relationship between drug concentration and QT interval, heart rate/pulse rate or blood pressure. Given an exposure-response dataset, the tool fits each model structure to the observed data.

CAR Estimation, Variable Selection, and Regression
The "care" package implements the CAR regression approach
described in Zuber and Strimmer (2010).  CAR scores measure the
correlations between the response and the
Mahalanobis-decorrelated predictors.  The squared CAR score is
a natural measure of variable importance and provides a
canonical ordering of variables - see
http://arxiv.org/abs/1007.5516 for details. This package
provides functions for estimating CAR scores, for variable
selection using CAR scores, and for estimating corresponding
regression coefficients. Both shrinkage as well as empirical
estimators are available.
