This function will generate ordered beta random variates given values for the mean (mu), dispersion (phi) and cutpoints governing the ratio of degenerate (discrete) to continuous responses.
rordbeta(n = 100, mu = 0.5, phi = 1, cutpoints = c(-1, 1))
n
|
Number of variates to generate. |
mu
|
Value of the mean of the distribution. Should be in the (0,1) interval (cannot be strictly equal to 0 or 1). If length is greater than 1, should be of length n.
|
phi
|
Value of the dispersion parameter. Should be strictly greater than 0. If length is greater than 1, should be of length n.
|
cutpoints
|
A vector of two numeric values for the cutpoints. Second value should be strictly greater than the first value. |
A vector of length n of variates from the ordered beta distribution.
