Fitted Object

Description

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

Value

fix.coef named vector of fixed parameters, beta, of the model.
random.coef named vector of random parameters, u, of the model.
penalty named vector of penalty values for the random parts of the model.
var.fix estimated variances of the fixed components, beta, of the model.
var.random estimated variances of the predicted values of random components, u, of the model.
log.lik.margin.start initial value of the marginal log-likelihoods for survival time (t-) and calendar time (b-) directions.
log.lik.margin the value of the marginal log-likelihoods for t- and b- directions 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, for each t- and b- direction. It is needed for plotting of the smooth components.
deviation.frame data frame with named columns, according to the names of the varying coefficients, for each t- and b- direction. It is needed for plotting of the confidence bands of the smooth components.
grid.frame data frame with two columns, the first for survival time and the second for the birth 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).
