Session Notes:
Numeric doesn't do what we want (although it's great for what it does do)
Patrick likes Stata
- Many things can do what we want in SQL
A story by Patrick Multiple systems estimation
- Find intersections of lists
- Create list of presence/absence in the other lists
- Estimate what lies outside
Suggestion from Numarray folks
- Use recarray
- Mutable values, not mutable shape
- Perry describes record arrays in detail (sorry, I didn't get this down...)
Suggestion by Jeff/Abhay
Use Metakit https://www.equi4.com/metakit/
Use R (like S-Plus)
R + Python has problems. Patrick tells of difficulties passing data between Python and R, even simple stuff like small matrices -- R gives back data errors (roughly: "I don't understand what this is").
