blm 2.4.4

Added formula accessor; Made output of predict a vector; Use printCoefmat in the summary function; Created crude.risk function; Added log-likelihood method; Added dependency on stats4; References and CITATION to JSS paper

blm 2.4.3

Corrected bug in stratification variable in variance calculation for blm (function: vcov.influence.blm.strata); update predict method so response variable is not necessary

blm 2.4.2

Added risk.exposure.plot; removed excess.risk function; updated vignette with example for this plot

blm 2.4.1

Removed dev directory

blm 2.4

Added initialization parameters in influence methods

Modified summary method to shorten print out of t and p-values

Added aarp data set

blm 2.3

Fixes to vcov method to handle big matrices

Correction to gof function and addition of adjustment for weighted estimates

blm 2.2

Added warn argument to suppress warnings thrown when testing for feasible parameters

Function excess.risk added. Computes binned excess risk by a grouping variable. Useful for diagnosing functional relationship between risk and explanatory variable

Correction to variance calculation to include case status as a stratification variable for case-control studies

Revised vignette includes description of use of the excess.risk function

Added likelihood ratio test for hypothesis testing with cohort data (method LRT

Added leverage and displacement functions for blm and lexpit models to diagnose the model fit

blm 2.1

The constrained optimization procedure is now done in two stages for LEXPIT for the linear and expit components. This has the benefit of reducing constraints to linear piece where all inequalities will be linear in the parameters

Naming of ci changed to confint

The hosmerlem function has been changed to gof

The gof.pearson function has been added to compute Pearson's goodness-of-fit test

A revised vignette reflects the changes in 2.1
