Results presentation: HPD regions (for the time elapsed between parameters)
This page allows you to view highest posterior density (HPD) regions for
the time elapsed between any pair of parameters you choose. You may
also set the percentage at which the HPD region is calculated.
Accessing this page
This page may be accessed from the format and
parameter selection page when "HPD regions" is selected as the results
presentation type.
Description
On this page, the HPD regions (computed at a particular percentage) indicate
the most likely range(s) for the length for the elapsed time between the
two select parameters. BCal forms the interval (or intervals) by
choosing the lengths with the highest posterior probabilities and summing
their probabilities until the total probability included in the intervals
corresponds to the prescribed percentage. In this manner, any length
included in a reported HPD region has a higher posterior probability than
any length outside the region.
By default HPD regions are calculated at 95%. You may calculate
them at another percentage using the form below the table in which the
results are presented. Simply type in the new percentage and select
"Submit", the HPD region will be recalculated with the percentage you provided.
You may return to the format and parameter
selection page by selecting the "Back" button. Your choice of
format and parameters will be restored.
