Description Usage Arguments Details Value Author(s) References See Also Examples

Probability under uniform that profiles share same change-point location

1	CardE0(n,k,K,unif=TRUE)

`n`	Integer giving length of datasets.
`k`	Vector of integers giving change-point number of datasets.
`K`	Vector of integers giving number of segments in segmentation of each profile.
`unif`	Boolean stating whether prior on segmentation is uniform given K. If false then prior favors segments of equal length.

Returns the probability under the uniform that profiles of length n have their k[i]th change-point at same location when segmented into in K[i] segments.

A numeric object giving the prior probability of E0.
