params [K-1 by K+B] by 6. There are six values returned: 0.025, 0.05, mean, 0.50 (median),
0.95, 0.975 quantiles from the iterations. (0.025, 0.975) are used to construct 95
likewise (0.05, 0.95) can be used to construct 90
output: plot window can grow quite large depending on the number of states.
[K-1 by K+B] panes.
output: outputs statements of 90
and each X input coefficients (if any of the K-1 coefficients for a variable are significant then that
variable is deemed signficant.)
