EventTrio2t

class poisson_approval.EventTrio2t(candidate_x, candidate_y, candidate_z, tau)[source]

A 3-candidate almost-tie of the type (X - 1, X - 1, X).

Notes

We consider the trios of type 1, i.e. situations where S_x + 1 = S_y + 1 = S_z.

For parameters and attributes, cf. Event.

Examples

>>> from fractions import Fraction
>>> from poisson_approval import TauVector
>>> tau = TauVector({'a': Fraction(1, 10), 'ab': Fraction(6, 10), 'c': Fraction(3, 10)})
>>> EventTrio2t(candidate_x='a', candidate_y='b', candidate_z='c', tau=tau)
