Density, distribution function, quantile function and random
generation for the Beta distribution with parameters shape1
and
shape2
(and optional non-centrality parameter ncp
).
Value
dbeta
gives the density, pbeta
the distribution
function, qbeta
the quantile function, and rbeta
generates random deviates.
Invalid arguments will result in return value NaN
, with a warning.
The length of the result is determined by n
for
rbeta
, and is the maximum of the lengths of the
numerical arguments for the other functions.
The numerical arguments other than n
are recycled to the
length of the result. Only the first elements of the logical
arguments are used.
Examples
rbeta2(3, c(0.1,0.5,0.9),0.1)
