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. |
