CRAN bug release

Fix a bug with normal random effects.

CRAN release 1.4.0

This is a major release with the inclusion of several new features.

• Smooth accelerated failure time models have now been implemented, including natural splines and time-dependent acceleration factors.
• Standardised estimators (e.g. survival, survival differences and attributable fractions) for unclustered and clustered data.
• Predictions for survival in the uncured.

There have also been several bug fixes.

CRAN release 1.3.4

This is a substantial update for modelling of clustered time-to-event data.

New features:

• Added -log link (for additive hazards models) and Aranda-Ordaz link
• Added Z design matrix for random effects (e.g. random slopes). The current implementation only includes univariate random effects.
• Added both adaptive and non-adaptive quadrature for normal random effects
• Added robust standard errors for clustered data
• Experimental support for clustered data with left-truncation.

Bug fixes include:

• Can now include parametric smoothers in the formula

C++:

• Refactored stpm2 now includes the link as a data member, rather than using a template parameter and inheritance. This decreased the binary size by about a half.

New CRAN release

Incremental release, including (i) a bug fix for stpm2 plots and (ii) an implementation for marginal estimators for the frailty models.

Second CRAN release

Re-factored version for CRAN. This includes an important bug fix for pstpm2 and an initial release for frailty models and normal random effects.
