Migrating from Stata to Python
I have absolutely no clue what any of those do, but NumPy and SciPy. Maybe Sage or SymPy.
Some coworkers who have been struggling with Stata 11 are asking for my help to try to automate their laborious work. They mainly use 3 commands in Stata:

tsset  (sets a time series analysis)

as in: tsset year_column, yearly

varsoc (Obtain lag-order selection statistics for VARs)

as in: varsoc column_a column_b

vec (vector error-correction model)

as in: vec column_a  column_b, trend(con) lags(1) noetable

Does anyone know any scientific library that I can use through python for this same functionality?
