The INIT statement sets initial values for parameters in the optimization. You can specify any number of INIT statements.
Each initvalue is written as a parameter or parameter list, followed by an optional equality operator (=), followed by a number:
parameter <=> number
If you also specify the BAYES statement, the INIT statement also initializes the Markov chain Monte Carlo (MCMC) algorithm. In particular, the INIT statement does one of the following:
It initializes the tuning phase (this also includes the PROPCOV option).
It initializes the sampling phase, if there is no tuning phase.
