plot.dynreg | R Documentation |
This function plots the non-parametric cumulative estimates for the additive risk model or the test-processes for the hypothesis of constant effects with re-sampled processes under the null.
## S3 method for class 'dynreg' plot( x, type = "eff.smooth", pointwise.ci = 1, hw.ci = 0, sim.ci = 0, robust = 0, specific.comps = FALSE, level = 0.05, start.time = 0, stop.time = 0, add.to.plot = FALSE, mains = TRUE, xlab = "Time", ylab = "Cumulative coefficients", score = FALSE, ... )
x |
the output from the "dynreg" function. |
type |
the estimator plotted. Choices "eff.smooth", "ms.mpp", "0.mpp" and "ly.mpp". See the dynreg function for more on this. |
pointwise.ci |
if >1 pointwise confidence intervals are plotted with lty=pointwise.ci |
hw.ci |
if >1 Hall-Wellner confidence bands are plotted with lty=hw.ci. Only 0.95 % bands can be constructed. |
sim.ci |
if >1 simulation based confidence bands are plotted with lty=sim.ci. These confidence bands are robust to non-martingale behaviour. |
robust |
robust standard errors are used to estimate standard error of estimate, otherwise martingale based estimate are used. |
specific.comps |
all components of the model is plotted by default, but a list of components may be specified, for example first and third "c(1,3)". |
level |
gives the significance level. |
start.time |
start of observation period where estimates are plotted. |
stop.time |
end of period where estimates are plotted. Estimates thus plotted from [start.time, max.time]. |
add.to.plot |
to add to an already existing plot. |
mains |
add names of covariates as titles to plots. |
xlab |
label for x-axis. |
ylab |
label for y-axis. |
score |
to plot test processes for test of time-varying effects along with 50 random realization under the null-hypothesis. |
... |
unused arguments - for S3 compatibility |
