summary()
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.
