rbeta2(n, c, d, scale)

summary_beta2(c, d, scale, output = "list", ...)

Arguments

x,q

vector of quantiles

c,d

non-negative shape parameters

scale

non-negative scale parameter

log

logical; if true, returns the logarithm of the result

...

other arguments passed to FDist

p

vector of probabilities

n

number of observations to be simulated

output

type of the summary_beta2 output: "list" to return a list, "pandoc" to print a table

Details

The Beta distribution of the second kind with shape parameters c>0 and d>0 and scale parameter k>0 is the distribution of k*(U/(1-U)) where U is a random variable following the Beta distribution with shape parameters c and d.

Value

dbeta2 gives the density, pbeta2 the distribution function, qbeta2 the quantile function, and rbeta2 generates random observations, and summary_beta2 returns a summary of the distribution.

Note

Beta2Dist is a generic name for the functions documented.
