To load initial values after compiling the 3 chains, you need to select drag a box over the term list then seelct load inits. After doing this for each chain, you may have to select gen inits until the bottom left corner of the screen reads initial values generated, model initialized (Fig. 9.5).
#Initial values for Markov chains.
