Description: Estimates time varying regression effects under Cox type models in
survival data using classification and regression tree. The codes in this package were
originally written in S-Plus for the paper "Survival Analysis with Time-Varying Regression
Effects Using a Tree-Based Approach," by Xu, R. and Adak, S. (2002) <doi:10.1111/j.0006-341X.2002.00305.x>, Biometrics, 58: 305-315.
Development of this package was supported by NIH grants AG053983 and AG057707,
and by the UCSD Altman Translational Research Institute, NIH grant UL1TR001442.

Title: Concurrent Multivariate Models with Time-Varying Coefficients
Description: Provides a hypothesis test and variable selection algorithm for use in time-varying, concurrent regression models. The hypothesis test function is also accompanied by a plotting function which will show the estimated beta(s) and confidence band(s) from the hypothesis test. The hypothesis test function helps the user identify significant covariates within the scope of a time-varying concurrent model. The plots will show the amount of area that falls outside the confidence band(s) which is used for the test statistic within the hypothesis test.

Title: Date calculations and manipulation
Author: Tony Plate, Jeffrey Horner, Lars Hansen
Description: Date sequence, relative date calculations, and date manipulation with business days
and holidays.  Works with Date and POSIXt classes.
