summary.joint: Summarise a random effects joint model fit

Description

Generic function used to produce summary information from a fitted random effects joint model as represented by object of class joint.

Usage

## S3 method for class 'joint':
summary(object, variance, \dots)

Arguments

object

an object inheriting from class joint representing a fitted random effects joint model.

variance

should the variance components be output as variances or standard deviations? Defaults to variance = TRUE.

...

further arguments for the summary

Value

• an object inheriting from class summary.joint with all components included in object (see joint for a full description of the components) plus the following components:
• nobs
  the total number of (typically longitudinal) observations (i.e. rows in an unbalanced data set).
• ngrps
  the number of groups in the analysed dataset, often individual subjects.

Examples

data(heart.valve)
heart.surv <- UniqueVariables(heart.valve, 
                              var.col=c("fuyrs","status"),
                              id.col="num")
heart.long <- heart.valve[, c("num", "time", "log.lvmi")]
heart.cov <- UniqueVariables(heart.valve, 
                             c("age", "hs", "sex"), 
                             id.col = "num")
heart.valve.jd <- jointdata(longitudinal = heart.long, 
                            baseline = heart.cov, 
                            survival = heart.surv, 
                            id.col = "num", 
                            time.col = "time")
fit <- joint(data = heart.valve.jd, 
             long.formula = log.lvmi ~ 1 + time + hs, 
             surv.formula = Surv(fuyrs,status) ~ hs, 
             model = "intslope")
summary(fit)
