EstimationTools 2.4.0 Unreleased

  • New!!! genetic algorithm (GA::ga) implemented in maxlogL.
  • Custom optimization interface enabled (tests required).

EstimationTools 2.3.0 Unreleased

  • New coef method implemented.
  • Link functions updated, precision problems solved.
  • Link functions specified in summary (maxlogLreg) and print methods.
  • Bug in answer class object in DEoptim fixed.

EstimationTools 2.2.0 Unreleased

  • TTT_hazard_shape was implemented as method for classes EmpiricalTTT and formula objects.
  • Hazard_Shape function deprecated. We implemented a ‘print’ method for TTT_hazard_shape objects.
  • plot.HazardShape: More flexibility in plot options enabled.
  • Bug in se.fit(predict method) fixed.

EstimationTools 2.1.1 Unreleased

  • Default value for data (NULL) in order to handle data inside another function (use with apply family) in TTT functions.
  • New data sets and examples for them added. They were also referenced.

EstimationTools 2.1.0 2021-03-10

  • Function for hazard shape estimation implemented. A plot method was also implemented.

EstimationTools 2.0.2 Unreleased

  • Empirical TTT with numerical (grouped) covariate.

EstimationTools 2.0.1 Unreleased

  • Bug fixed. Formula handle with survival objects without factor classification in TTTE_Analytic is fixed.

EstimationTools 2.0.0 2020-08-03

  • ‘EstimationTools’ was build in R 4.0.2.

  • We have implemented noncentrality parameter detection. This parameter must be named ncp in the distribution.

  • We have implemented computation and plots of empirical total time on test (TTT).

  • Standard error computation is now performed inside maxlogL and maxlogLreg.

  • Standard errror value is now stored in the list case named ‘fit’. It can be called typing objectname$fit$StdE, where ‘objectname’ is the object where the model is stored.

  • The new method (function) ‘bootstrap_maxlogL’ was created for standard error computation through bootstrap.

  • ‘summary’ method only reports results. It does not perform any computation, bootstrap through ‘summary’ function has been deprecated.

  • We have made a careful spelling check in our documentation.
