I think you mat be confusing the class with the module.

When you write:

     import Univariate

you're importing the module.

If the module is called "Univariate" and the class within the module is
called "Univariate" then you should either write:

     import Univariate
     x = Univariate.Univariate(a) # the class Univariate in the module 
Univariate

or:

     from Univariate import Univariate
     x = Univariate(a)

Incidentally, it's recommended that module names use lowercase, so that
would be:

     import univariate
     x = univariate.Univariate(a)

or:

     from univariate import Univariate
