assessStationarity bug

[spedygiorgio]

I have a question, however, about the assessStationarity package. It works well if there are no zeros in the frequency matrix but throws an NaN when zeros exist.

Below I provide two sequences vectors. They both come from Brian O’Conner’s article (https://people.ok.ubc.ca/brioconn/sequential/sequential.html). The first one is the original sequence and the second one includes a few more codes that eliminates the zero cells. Any chance that assessStationarity routine might include a switch that allows estimation of stationarity when zeros exist? Thanks very much!

Best,

Joe
