evpdf
Extreme value probability density function
Syntax
Y = evpdf(X,mu,sigma)
Description
Y = evpdf(X,mu,sigma)
returns the pdf of
the type 1 extreme value distribution with location parameter mu
and
scale parameter sigma
, evaluated at the values
in X
. X
, mu
,
and sigma
can be vectors, matrices, or multidimensional
arrays that all have the same size. A scalar input is expanded to
a constant array of the same size as the other inputs. The default
values for mu
and sigma
are 0
and 1
,
respectively.
The type 1 extreme value distribution is also known as the Gumbel
distribution. The version used here is suitable for modeling minima;
the mirror image of this distribution can be used to model maxima
by negating X
. See Extreme Value Distribution for more details. If x has
a Weibull distribution, then X = log(x)
has the type 1 extreme value distribution.
