Initiating enter sequence as 0 success 0 failures for prior prediction table

[jvli4n]

.tablePredictions2LS now assumes 0 successes and 0 failures in case no data sequence is specified, so the analysis does not crash.

Nice, it solves the issue quite convinietly. I did not see any new bugs, but I noticed a couple of additional inconsistencies, could you also address those?

Screenshot1:

• Prior Predictive Performance: Predictions Table --- It's arguable how good is a prediction from hypotheses without any data, I think the table should be empty (i.e., correspond to the empty figure - you can add a return statement after the table is initialized)
• Sequential Analysis: Updating Table --- Now incorrectly states "1 Observation"

Screenshot2:

• Posterior Predictions: The tables are generated while the Figure is empty. I think the correct behavior is having the figure output too as prior = posterior, and prior predictions = posterior predictions (I think there is a switch in the code that creates empty dataset to generate those figures in the same functions if type = "prior")

Maybe you could quickly check the Binomial Estimation whether you see something there too.

The code looks and the results are now consistent. The only very minor nitpic is that in the Prior Predictive Performance Section, the Predictions table should have no rows when no data are specified.
