Density function for the beta distribution, an alternative parameterization

The beta distribution is parameterized using the mean and a function sigma_mu that computes the variance as a function of the mean

dbeta1(x, mu, pSig = par_sigma_abc())

Arguments

x

a vector of quantiles

mu

the mean value for the distribution (0 <= mu <= 1)

pSig

parameters to dispatch the S3 function sigma_mu

Value

a numeric vector of length(x)
