sage.stats.r.ttest(x, y, conf_level=0.95, **kw)[source]

T-Test using R.

INPUT:

  • x, y – vectors of same length

  • conf_level – confidence level of the interval, [0,1) in percent

OUTPUT:

Tuple: (p-value, R return object)

EXAMPLES:

sage: a, b = ttest([1,2,3,4,5],[1,2,3,3.5,5.121]); a  # abs tol 1e-12  # optional - rpy2
0.9410263720274274
>>> from sage.all import *
>>> a, b = ttest([Integer(1),Integer(2),Integer(3),Integer(4),Integer(5)],[Integer(1),Integer(2),Integer(3),RealNumber('3.5'),RealNumber('5.121')]); a  # abs tol 1e-12  # optional - rpy2
