statsmodels.duration.hazard_regression.rv_discrete_float¶

class
statsmodels.duration.hazard_regression.
rv_discrete_float
(xk, pk)[source]¶ A class representing a collection of discrete distributions.
 Parameters
 xk2d array_like
The support points, should be nondecreasing within each row.
 pk2d array_like
The probabilities, should sum to one within each row.
Notes
Each row of xk, and the corresponding row of pk describe a discrete distribution.
xk and pk should both be twodimensional ndarrays. Each row of pk should sum to 1.
This class is used as a substitute for scipy.distributions. rv_discrete, since that class does not allow noninteger support points, or vectorized operations.
Only a limited number of methods are implemented here compared to the other scipy distribution classes.
Methods
mean
()Returns a vector containing the mean values of the discrete distributions.
rvs
([n])Returns a random sample from the discrete distribution.
std
()Returns a vector containing the standard deviations of the discrete distributions.
var
()Returns a vector containing the variances of the discrete distributions.
