R: Summary methods for an 'etm' object

summary.etm {etm} | R Documentation

## Summary methods for an 'etm' object

### Description

Summary method for objects of class `etm`

### Usage

    ## S3 method for class 'etm'
    summary(object, tr.choice,
            ci.fun = "linear", level = 0.95, times, ...)
    ## S3 method for class 'summary.etm'
    print(x, ...)

### Arguments

`object` | An object of class `etm`.
`tr.choice` | Character vector of the form 'c("from to","from to")' specifying which transitions should be summarized. Default to all the transition probabilities
`ci.fun` | A character vector specifying the transformation to be applied to the pointwise confidence intervals. It could be different for each transition probability, though if `length(ci.fun) != number of transitions`, only `ci.fun[1]` will be used. The function displays the transition probabilities in the following order: first the direct transitions in alphabetical order, e.g., 0 to 1, 0 to 2, 1 to 2, ..., then the state occupation probabilities in alphabetical order, e.g., 0 to 0, 1 to 1, ... The possible transformations are "linear", "log", "log-log" and "cloglog". Default is "linear".
`level` | Level of the two-sided confidence intervals. Default is 0.95.
`x` | A `summary.cpf` object
`times` | Time points for which estimates should be returned. Default to all transition times.
`...` | Further arguments

### Value

A list of data.frames giving the transition probability and stage occupation probability estimates. List items are named after the possible transition.

`P` | Transition probability estimates
`var` | Variance estimates
`lower` | Lower confidence limit
`upper` | Upper confidence limit
`time` | Transition times
`n.risk` | Number of individuals at risk of experiencing a transition just before time t
`n.event` | Number of events at time t
