The pZOIP function defines the cumulative distribution function of the ZOIP distribution.

q |
quantiles vector. |
mu |
vector of location parameters. |
sigma |
vector of scale parameters. |
p0 |
parameter of proportion of zeros. |
p1 |
Parameter of proportion of ones. |
family |
choice of the parameterization or distribution, family = 'R-S' parameterization beta distribution Rigby and Stasinopoulos, 'F-C' distribution Beta parametrization Ferrari and Cribari-Neto, 'Original' Beta distribution classic parameterization, 'Simplex' simplex distribution. |
lower.tail |
logical; if TRUE (default), probabilities will be P [X <= x], otherwise, P [X> x]. |
log.p |
logical; if TRUE, the probabilities of p will be given as log (p). |
x has ZOIP distribution with shape parameters "μ", scale "σ", proportion of zeros "p0" and proportion of ones " p1 ", has density: p0 if x = 0, p1 if x = 1, (1-p0-p1) f (x; μ, σ) yes 0 <x <1.
where p0 ≥ 0 represents the probability that x = 0, p1 ≥ 0 represents the probability that x = 1, 0 ≤ p0 + p1 ≤ 1 and f (x; μ, σ) represents some of the functions of probability density for proportional data, such as the beta distribution with its different parameterizations and the simplex distribution.
When family =' R-S 'uses the beta distribution with beta parameterization Rigby and Stasinopoulos (2005) which has a beta distribution function. μ is the parameter of mean and shape, plus σ is the dispersion parameter of the distribution. family =' F-C 'distribution Beta parametrization Ferrari and Cribari-Neto (2004), where σ = φ, φ is a precision parameter. family =' Original 'beta distribution original parametrization where μ = a, a parameter of form 1; σ = b, b parameter of form 2. family =' Simplex 'simplex distribution. proposed by Barndorff-Nielsen and Jørgensen (1991)
