Coupled Hidden Markov Models
This package implements an exact and a variational inference for coupled Hidden Markov Models applied to the joint detection of copy number variations.
You can install the released version of CHMM from CRAN with:
install.packages("CHMM")
This is a toy example (1 000 positions of 5 correlated samples) which shows you how to use the package.
```{r example} data(toyexample)
resCHMM <- coupledHMM(X = toydata, nb.states = 3, S = cor(toystatus), omega.list = c(0.3, 0.5, 0.7, 0.9))
info <- clusterseg(resCHMM$status) ```
