Fitted jmodelTM Object
Description
An object returned by the jmodelTM
function, inheriting from class jmodelTM
and representing a fitted joint model for survival and longitudinal data. Objects of this class have methods for the generic functions AIC
, BIC
, logLik
, print
, summary
, and vcov
.
Value
The following components must be included in a legitimate jmodelTM
object.
coefficients |
a list with the estimated parameters. The list is consist of the following components: |
- beta
the vector of estimated coefficients for the fixed effects in the linear mixed-effects model.
- phi
the vector of estimated coefficients for the covariates other than the covariate associated with the longitudinal process in the survival model.
- alpha
the estimated coefficient for the covariate associated with the longitudinal process in the survival model.
- Ysigma
the estimated measurement error standard deviation for the linear mixed-effects model.
- BSigma
the estimated variance-covariance matrix of the random effects.
- lamb
a numeric matrix with two columns: the first column contains the unique observed survival times in ascending order; the second column contains the corresponding estimated baseline hazard values.
Vcov |
the variance-covariance matrix evaluated at the estimated parameter values. |
logLik |
the log-likelihood (the joint likelihood) value. |
est.bi |
the estimated values for the random effects |
call |
a list containing an image of the |
numIter |
the number of iterations used in the EM algorithm. |
convergence |
the convergence indicator: if |
control |
the value of the |
time.SE |
the CPU time used to compute the standard error estimates, i.e. the time use to compute the variance-covariance matrix for the parameter estimates. |
N |
the total number of repeated measurements for the longitudinal outcome. |
n |
the number of sample units. |
d |
the censoring indicator: 0 denotes censored survival time; 1 denotes observed survival time. |
rho |
the transformation parameter used for the survival model. |
