WebThe probability density function for the t distribution is. P ( x, d f) = Γ ( d f + 1 2) π d f Γ ( d f 2) ( 1 + x 2 d f) − ( d f + 1) / 2. The t test is based on an assumption that the data come from a Normal distribution. The t test provides a way to test whether the sample mean (that is the mean calculated from the data) is a good ...

Instead of indexing: stock = tup[0] industry = tup[1] use tuple assignment: stock, industry, *_ = tup But note that this only works in Python 3. In Python 2 you can write: stock, industry = tup[:2] and I think this is still clearer than indexing.
