show() method for Recur class objects prints in the same order as the
internally sorted ID's.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. #7summary() method for Recur() objects.time_class to Recur() object.id slot of Recur() object to unique ID's.adjustRiskset = FALSE is specified.first_idx and last_idx in Recur object.deriv method from splines2 objects for derivatives instead of
extraction of attributions.variance = "none" to return sample MCF estimates without
variance estimates.plot() method for mcf objects for a more minimal output
by default.Added 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.
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.
numRisk (the size of risk set) for tied censoring times in
mcf.formula objects returned from method mcf.formula. Thank William
Anderson (wnilesanderson AT gmail.com) for bug reporting with detailed
examples.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.
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.
Survr(ID, time, event) ~ 1 for modeling baseline rate
function using gamma frailty model in function rateReg without specifying
any covariate.plot,mcf.formula (previously
plot,sampleMcf) method.baseRate for estimated baseline rate function instead of
the estimated coefficients of spline bases.confint by specifying the correct standard error column.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.
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.
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.
Implementation of spline baseline rate function.
Added function AIC and BIC.
Renamed main function name from heart to rateReg and added new argument.
Updated object class of fitted model.
Replaced sample simulated dataset for demonstration.
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.
