Uses the current group membership to estimate the probabilities.
mStep(Z, D)an \(n \times q\) matrix, where \(n\) is the number
of rows of dframe and \(q\) is the number of components in the
mixture. During the fitting \(Z_{ij}\) holds the currently estimated
probability that observation \(i\) belongs to component \(j\).
Commonly Z is initialized to a matrix of indicator columns for a
partition of the data.
