a `list`

containing:

k a

`integer`

, the number of nucleosomes.k_max a

`integer`

, the maximum number of nucleosomes obtained during the iteration process.it a

`vector`

of`integer`

of length`k`

, the variance of the forward reads for each nucleosome.nbState a

`integer`

, the number of changes of state.mu a

`matrix`

of`numeric`

with`k_max`

columns and`nbState`

row containing, in each row, the`mu`

values associated the the state identified by the row number.muHat a

`matrix`

of`numeric`

with`k_max`

columns and`k_max`

rows containing, in each row, the mean`mu`

values associated the number of nucleosomes detected. The row number corresponds to the number of nucleosomes detected.nbK a

`vector`

of length`k_max`

containing`integer`

, the number of iterations which detected a specific number of nucleosomes. The position in the vector correspond to the number of nucleosomes.
