R: Print a fitted msm model object

print.msm {msm} | R Documentation

## Print a fitted msm model object

### Description

Print a fitted msm model object

### Usage

    ## S3 method for class 'msm'
    print(x,covariates=NULL, digits=4, ...)
    printnew.msm(x, covariates=NULL, digits=4, ...)

### Arguments

`x` | Output from `msm`, representing a fitted multi-state model object.
`covariates` | Covariates for which to print “baseline” transition intensities or misclassification probabilities. See `qmatrix.msm` for more details.
`digits` | Minimum number of significant digits, passed to `format`. Defaults to 4.
`...` | Other arguments to be passed to `format`.

### Details

This is the new method of formatting msm objects for printing. The old method was based on printing lists of matrices. That produced a lot of wasted space for parameters which were zero, and it was difficult to match corresponding numbers between matrices. The new method presents all the transition intensities and covariate effects as a single compact table, and likewise for misclassification matrices.

Also in the old method, covariate effects were presented as log hazard ratios or log odds ratios. The log scale is more convenient mathematically, but unnatural to interpret. The new method presents hazard ratios for covariates on transition intensities and odds ratios for misclassification probabilities.

`printnew.msm` is an alias for `print.msm`.

### Value

The object returned by `print.msm` is a numeric matrix with one column for each estimate or confidence limit for intensities and their covariates, in the same arrangement as printed, but with the underlying numbers in full precision. The results formatted for printing are stored in the `"formatted"` attribute of the object, as a character matrix. These can alternatively be produced by `msm.form.qoutput`, which has no printing side-effect. `msm.form.eoutput` produces the same arrangement for misclassification probabilities instead of intensities.
