- Below is a Theorist session which I Copied into the clipboard
- and pasted directly into a text file for upload to post here.
- If you are working from a Macintosh, I believe you can reverse
- this process and see what I have been doing.
-
- (BTW, while I was copying the clipboard into this post, I got several
- beeps because some of the characters are invisible. I hope this does
- not mess up the transfer.)

- My question is the following. I would like to demonstrate
- that the Poisson function is a pdf in the sense that it sums
- to 1. Whereas I have been successfull in computing cumulative
- probabilities for the Poisson distribution when I supply
- constants for the variable and the parameter, Theorist seems
- to ignore me when I leave the variable and parameter as names
- and request a Transformation, Expand, Calculate, etc.
-
- Can this be done in Theorist? BTW, I am working with
- version 1.0. I would like to encourage my students to use
- Theorist if this is possible.
