Function to expand an existing q_matrix to a number of concealed states
expand_q_matrix(q_matrix, num_concealed_states, diff.conceal = FALSE)
updated q matrix
q_matrix
with only transitions between observed states.
number of concealed states, generally equivalent to the number of examined states in the dataset.
Boolean stating if the concealed states should be
different. E.g. that the transition rates for the concealed
states are different from the transition rates for the examined states.
Normally it should be FALSE
in order to avoid having a huge number of
