| jointModelObject {JM} | R Documentation |
An object returned by the jointModel function, inheriting from class jointModel and representing a fitted
joint model for longitudinal and time-to-event data. Objects of this class have methods for the generic functions
anova, coef, fitted, fixed.effects, logLik, plot, print,
random.effects, residuals, summary, and vcov.
The following components must be included in a legitimate jointModel object.
coefficients |
a list with the estimated coefficients. The components of this list are:
|
Hessian |
the Hessian matrix evaluated at the estimated parameter values. |
logLik |
the log-likelihood value. |
EB |
a list with components:
|
knots |
the numeric vector of the knots positions for the log times used in the B-splines approximation of the
log cumulative baseline hazard; returned only when method = "ch-GH" or method = "ch-Laplace". |
iters |
the number of iterations in the optimization algorithm. |
convergence |
convergence identifier: 0 corresponds to successful convergence, whereas 1 to a problem (i.e., when 1, usually more iterations are required). |
n |
the number of sample units. |
N |
the total number of repeated measurements for the longitudinal outcome. |
ni |
a vector with the number of repeated measurements for each sample unit. |
d |
a numeric vector with 0 denoting censored observation and 1 events. |
id |
the grouping vector for the longitudinal responses. |
x |
a list with the design matrices for the longitudinal and event processes. |
y |
a list with the response vectors for the longitudinal and event processes. |
data.id |
a data.frame containing the variables for the linear mixed effects model at the time of the
event. |
method |
the value of the method argument. |
termsY |
the terms component of the lmeObject. |
termsT |
the terms component of the survObject. |
formYx |
the formula for the fixed effects part of the longitudinal model. |
formYz |
the formula for the random effects part of the longitudinal model. |
formT |
the formula for the survival model. |
timeVar |
the value of the timeVar argument |
control |
the value of the control argument. |
call |
the matched call. |
