Description Usage Arguments Value
Two proposals: the function bmdl.MH.flip
proposes to flip a random
dimension, and the function bmdl.MH.swap
propose to swap between a
randomly chosen zero and a randomly chosen one.
1 2 3 | bmdl.MH.flip(X, month, current, meta, p, fit, penalty, nu, a, b1, b2, period)
bmdl.MH.swap(X, month, current, meta, p, fit, penalty, nu, a, b1, b2, period)
|
X |
A vector of length |
month |
A vector of length |
current |
A list of current changepoint model. Specifically,
|
meta |
A 0-1 indicator vector of length N, metadata indicator.
The first |
p |
The order of the AR process. |
fit |
For likelihood calculation, |
penalty |
For penalty function calculation, |
nu |
Prior variance scale of |
a |
The first and second parameters in the Beta-Binomial prior; only
used if |
b1 |
The b parameter in the Beta-Binomial prior of η, for un-documented times (i.e., times not in metadata). Default value is 239 for monthly data, and 19 for annual data. |
b2 |
The b parameter in the Beta-Binomial prior of η, for documented times (i.e., times in metadata). Default value is 47 for monthly data, and 3 for annual data. |
period |
Period of the seasonal cycle, 12 for monthly data, or 1 for annual data. |
A list of current changepoint model. Specifically,
list(eta, inference, change.eta)
, where inference
is the
output of the function bmdl.eta
.
