Density, distribution function, and random generation for the bivariate
chi-bar-squared distribution with mixing weights (conic intrinsic volumes) v
.
dbichibarsq(x, v) pbichibarsq(x, v) rbichibarsq(n, v)
x | two-entry vectors or two-column matrices. |
---|---|
v | vector of mixing weights (conic intrinsic volumes). |
n | number of observations. |
The output of dbichibarsq(x, v)
is either a number, if x
is a vector of length 2
, or a vector of length dim(x)[1]
such that the entries are the values of the density of the
bivariate chi-bar-squared distribution with weights v
in the
corresponding entry (row) of x
.
The output of pbichibarsq(x, v)
is either a number, if x
is a vector of length 2
, or a vector of length dim(x)[1]
such that the entries are the values of the cdf of the
bivariate chi-bar-squared distribution with weights v
in the
corresponding entry (row) of x
.
The output of rbichibarsq(n, v)
is either a number, if n==1
,
or a two-column matrix with n
rows such that the rows are
iid samples from the bivariate chi-bar-squared distribution with weights v
.
