The progress window gives information about the progress of calculations for Additional Estimands and for Custom Estimands. Calculation additional estimands and custom estimands takes a noticeable amount of time because only the model parameters for each MCMC observation are saved in memory. If you ask for a display of the posterior distribution of custom estimands or additional estimands (say indirect effects or implied covariances), the program has to calculate those estimands for each MCMC sample.

In the following example there are 69,501 MCMC observations in addition to any burn-in observations. Calculating the additional estimands for the first 27,144 observations took 4 seconds. Doing the rest of the calculations is estimated to take another 6 seconds. The estimated completion time is 13:47 (1:47 pm).
