%description
Kiener distributions K1, K2, K3, K4 and K7 to characterize distributions
with left and right, symmetric or asymmetric fat tails in finance,
neuroscience and other disciplines. Two algorithms to estimate the
distribution parameters, quantiles, value-at-risk and expected shortfall.
IMPORTANT: Standardization has been changed in versions >= 2.0.0 to get sd
= 1 when kappa = Inf rather than 2*pi/sqrt(3) in versions <= 1.8.6. This
affects parameter g (other parameters stay unchanged). Do not update if
you need consistent comparisons with previous results for the g parameter.
