reda 0.5.4

Minor changes

• The show() method for Recur class objects prints in the same order as the internally sorted ID's.
• Added a new argument named rhoMax to the function simEvent() for users to specify an upper bound of the rate function in case the function cannot determine an appropriate upper bound internally. #7

reda 0.5.3

Minor changes

• Added summary() method for Recur() objects.
• Added a new slot named time_class to Recur() object.
• Updated the id slot of Recur() object to unique ID's.

Bug fixes

• Fixed empty MCF estimates when adjustRiskset = FALSE is specified.
• Fixed slot first_idx and last_idx in Recur object.

reda 0.5.2

Minor changes

• Used deriv method from splines2 objects for derivatives instead of extraction of attributions.

reda 0.5.1

New features

• Added a new option variance = "none" to return sample MCF estimates without
  variance estimates.

Minor changes

• Removed titles in plot() method for mcf objects for a more minimal output
  by default.

reda 0.5.0

New features

• Add function Recur as a successor or function Survr for model formula
  response.

• Added a new package vignette introducing the function Recur.

• Added a new argument adjustRiskset to the method mcf.formula for
  specifying whether to adjust the size of risk set. The cumulative sample mean
  function estimates will be computed by setting adjustRiskset = FALSE.

• Added a new option of "CSV" for cumulative sample variance estimates to the
  argument variance of the method mcf.formula.

Major changes

• The function Survr is deprecated since this version and will be removed in
  future.

• Added implementation of nonparametric MCF estimates in C++ with help of
  Rcpp and replaced original implementation in R with the new
  implementation for a better computational performance.

Minor changes

• Updated testing suite by using tinytest instead of testthat.

Bug fixes

• Fixed numRisk (the size of risk set) for tied censoring times in
  mcf.formula objects returned from method mcf.formula. Thanks William
  Anderson (wnilesanderson AT gmail.com) for bug reporting with detailed
  examples.

reda 0.4.1

Bug fixes

• Fixed compiling errors when using clang.

reda 0.4.0

New features

• Added function simEvent and simEventData for simulating survival,
  recurrent event, and multiple event data from stochastic process point of
  view.
• Added function mcfDiff and mcfDiff.test for comparing two-sample MCFs by
  difference estimates over time and the pseudo-score tests.
• Added argument origin to function Survr for modeling processes with
  different time origins.
• Added variance estimates of sample MCF from bootstrap methods.

Major changes

• Updated checking rule of argument event of function Survr for modeling
  sample MCF of cost in addition to number of events.
• Updated Lawless and Nadaeu (1995) variance estimates in method mcf.formula
  for sample MCF.
• Renamed class sampleMcf to mcf.formula, rateRegMcf to mcf.rateReg,
  baseRateReg to baseRate.rateReg, summaryRateReg to summary.rateReg.

Minor changes

• Allowed formula Survr(ID, time, event) ~ 1 for modeling baseline rate
  function using gamma frailty model in function rateReg without specifying
  any covariate.

Bug fixes

• Fixed possible label mismatching in plot,mcf.formula (previously
  plot,sampleMcf) method.

reda 0.3.1

New features

• Added estimated baseline rate function and its confidence band, and
  corresponding plot method.

Major changes

• Updated function baseRate for estimated baseline rate function instead of
  the estimated coefficients of spline bases.

Bug fixes

• Fixed function confint by specifying the correct standard error column.

reda 0.3.0

New features

• Added M-spline for modeling baseline rate to function rateReg.
• Added argument check to function rateReg so that it is possible to skip
  the data checking step to slightly speed up the model fitting for cleaned
  data.
• Added option verbose to argument control of function rateReg to suppress
  all possible messages.
• Added variance estimates for sample MCF by Poisson process method, and
  confidence interval based on the asymptotic normality of MCF itself (in
  addition to the logarithm of MCF) to function mcf,formula-method.
• Allowed multiple categorical variables in function mcf,formula-method for
  the sample MCF for design with multiple factors.
• Added sample valve-seat dataset from Nelson (1995) for demonstration.

Major changes

• Borrowed the power from R package splines2 for piece-wise constant and
  splines based baseline rate function, and thus boosted the performance of
  reda in model fitting.
• Updated object class of fitted model, rateReg.
• Replaced generic function plotMcf with methods for function plot.
• Updated data checking procedure for a better performance.
• Added variable "gender" in sample simulated dataset, simuDat for a better
  demonstration of sample MCF function.

Minor changes

• Renamed all slot named boundaryKnots to Boundary.knots for consistency
  with spline functions.
• Updated vignettes for demonstration of new features.
• Added sample citation entry for reda.

reda 0.2.1

New features

• Implementation of spline baseline rate function.
• Added function AIC and BIC.

Major changes

• Renamed main function name from heart to rateReg and added new argument.
• Updated object class of fitted model.
• Replaced sample simulated dataset for demonstration.

Bug fixes

• Updated S4 method plotMcf,sampleMcf: Replaced show_guide with
  show.legend in function geom_text to incorporate updates in package
  ggplot2 v1.0.1.
• Minor updates that clear checking note from CRAN.
