EstimationTools 4.3.0

  • Fix log-likelihood in maxlogLreg().
  • Enable further input arguments for legend in plots of residuals.

EstimationTools 4.2.0

  • Implement plots of residuals (diagnostic plots).

EstimationTools 4.1.1

  • Implementation of residuals: Cox-Snell, randomized quantile residuals and martingale residuals.

EstimationTools 4.1.0

  • We implemented two functions to compute expected values.

EstimationTools 4.0.1

  • We fixed the hazard function routine implemented to compute hazard functions for any distribution.
  • We also implemented a routine to compute cumulative hazard functions for any distribution.
  • We fixed and updated the documentation.

EstimationTools 4.0.0

CRAN release: 2022-12-10

  • We changed the behaviour of plot.HazardShape function, its responsibility was splitted. Now, this function just plots the empirical TTT function, and we also created the legend.HazardShape to customize the legend options.
  • We fixed some examples in the documentation.

EstimationTools 3.0.0

  • EstimationTools was build in R 4.2.1.
  • From this version, maxlogLreg returns the censorship matrix. Check the documentation for further information about the censorship matrix.
  • We have implemented a wrapper (an API) of integration routines.

EstimationTools 2.4.0

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

EstimationTools 2.3.0

  • 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

  • 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

  • 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

CRAN release: 2021-03-10

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

EstimationTools 2.0.2

  • Empirical TTT with numerical (grouped) covariate.

EstimationTools 2.0.1

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

EstimationTools 2.0.0

CRAN release: 2020-08-03

  • EstimationTools was build in R 4.0.2.

  • We have implemented non-centrality parameter detection. This parameter must be named ncp in any custom 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.
