 the program:</p>
<p>(1) As the log-likelihood of a latent class model can have multiple maxima,
a careful choice of the initial values is crucial for ensuring convergence
toward the global maximum.  The program can be run without entering the
vector of initial values (see point 2).  However, we recommend to
systematically enter initial values in <code>B</code> and try different sets of
initial values.</p>
<p>(2) The automatic choice of initial values we provide requires the
estimation of a preliminary line
