TwoWaySurvfitObject {TwoWaySurvival} | R Documentation |
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.
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). |
