Cochran Armitage exact?

[#1]

I have data for a 5 year period. there is binary feature (registered/unregistered) represented by a column in the data.

I want to see if there is a trend for proportion unregistered items year by year across the 5 year period.

The Cochran Armitage trend test seems like the appropriate statistic (yes?). 

The the number of unregistered items is single digits for multiple years, and is even zero one year.  It would seem I need the Cochrane Armitage Exact test, but don't think it is available (JMP14.3.0 for Mac)

Am I missing something?

You must be sure that the data columns that you use in the Y and X analysis roles use the Ordinal modeling type before you initiate this analysis. Then select Analyze > Fit Y by X, select the binary response and click Y. Select the year data column and click X. Click the red triangle at the top and select the trend test.
