marginal_probabilities
returns a vector with the marginal
probabilities of a categorical time series

An object of type |
Given a CTS of length T
with range \mathcal{V}=\{1, 2, \ldots, r\}
,
\overline{X}_t=\{\overline{X}_1,\ldots, \overline{X}_T\}
, the function computes the
vector \widehat{\boldsymbol p} =(\widehat{p}_1, \ldots, \widehat{p}_r)
,
with \widehat{p}_i=\frac{N_i}{T}
, where N_i
is the number
of elements equal to i
in the realization \overline{X}_t
.
A vector with the marginal probabilities.
