OneWaySurvfitObject {TwoWaySurvival}R Documentation

Fitted one-dimensional Object

Description

An object of class 'OneWaySurvfit' returned as a list by the 'OneWaySurvfitCreate' function and representing a fitted one-way hazard model with varying coefficients. It has methods for generic functions print, plot and summary.

Value

fix.coef named vector of not penalized parameters of the model. It has the value 'NULL' if B-spline bases are chosen for modelling.
random.coef named vector of penalized parameters of the model.
penalty named vector of penalty values for the random parts of the model.
var.fix estimated variances of not penalized parameters of the model. It has the value 'NULL' if B-spline bases are chosen for modelling.
var.random estimated variances of the predicted values of (penalized) random components of the model.
log.lik.margin.start initial value of the marginal log-likelihood.
log.lik.margin the value of the marginal log-likelihood at optimum.
df estimated degrees of freedom for the parts of the model.
df.total total or summed estimated degrees of freedom.
niter.epoch number of outer loops in optimization routine.
varying.frame data frame with named columns, according to the names of the varying coefficients. It is needed for plotting of the smooth components.
deviation.frame data frame with named columns, according to the names of the varying coefficients. It is needed for plotting of the confidence bands of the smooth components.
grid.frame data frame with just one column, for survival time, needed for plotting issues.
p number of covariates; for factors including their categories (excluding reference category).
factor.names covariate names; for factors the names of categories (excluding reference category).
