se constant intensities (which change at common times)</h2>
<p><code>msm</code> provides a shorthand for these models where the intensities depend on the time period.</p>
<p>Supply the times when all intensities change in the <code>pci</code> argument. <code>msm</code> will automatically construct a categorical covariate indicating the time period, impute artificial observations at the change times, and construct and fit a <code>censor</code> model to calculate and maximise the correct likelihood.</p>
