Transf_gen
(kls, func, funcinv, *args, **kwargs)[source]¶ a class for non-linear monotonic transformation of a continuous random variable
Methods
cdf
(x, *args, **kwds)Cumulative distribution function of the given RV.
entropy
(*args, **kwds)Differential entropy of the RV.
expect
([func, args, loc, scale, lb, ub, …])Calculate expected value of a function with respect to the distribution by numerical integration.
fit
(data, *args, **kwds)Return MLEs for shape (if applicable), location, and scale parameters from data.
fit_loc_scale
(data, *args)Estimate loc and scale parameters from data using 1st and 2nd moments.
freeze
(*args, **kwds)Freeze the distribution for the given arguments.
interval
(alpha, *args, **kwds)Confidence interval with equal areas around the median.
isf
(q, *args, **kwds)Inverse survival function (inverse of sf) at q of the given RV.
logcdf
(x, *args, **kwds)Log of the cumulative distribution function at x of the given RV.
logpdf
(x, *args, **kwds)Log of the probability density function at x of the given RV.
logsf
(x, *args, **kwds)Log of the survival function of the given RV.
mean
(*args, **kwds)Mean of the distribution.
median
(*args, **kwds)Median of the distribution.
moment
(n, *args, **kwds)n-th order non-central moment of distribution.
nnlf
(theta, x)Return negative loglikelihood function.
pdf
(x, *args, **kwds)Probability density function at x of the given RV.
ppf
(q, *args, **kwds)Percent point function (inverse of cdf) at q of the given RV.
rvs
(*args, **kwds)Random variates of given type.
sf
(x, *args, **kwds)Survival function (1 - cdf) at x of the given RV.
stats
(*args, **kwds)Some statistics of the given RV.
std
(*args, **kwds)Standard deviation of the distribution.
support
(*args, **kwargs)Return the support of the distribution.
var
(*args, **kwds)Variance of the distribution.
Properties
Get or set the RandomState object for generating random variates.
