VGAM (version 1.1-12)

N1binom: Linear Model and Binomial Mixed Data Type Distribution

Description

Density, and random generation for the (four parameter bivariate) Linear Model--Bernoulli copula distribution.

Usage

dN1binom(x1, x2, mean = 0, sd = 1, prob, apar = 0,
         copula = "gaussian", log = FALSE)
rN1binom(n, mean = 0, sd = 1, prob,
         apar = 0, copula = "gaussian")

Value

dN1binom gives the probability density/mass function,

rN1binom generates random deviate and returns a two-column matrix.

Arguments

x1, x2

vector of quantiles. The valid values of x2 are \(0\) and \(1\).

n

number of observations. Same as rnorm.

copula

See N1binomial.

mean, sd, prob, apar

See N1binomial.

log

Logical. If TRUE then the logarithm is returned.

Examples

if (FALSE) { 
nn <- 1000;  apar <- rhobitlink(1.5, inverse = TRUE)
prob <- logitlink(0.5, inverse = TRUE)
mymu <- 1; sdev <- exp(1)
mat <- rN1binom(nn, mymu, sdev, prob, apar)
bndata <- data.frame(y1 = mat[, 1], y2 = mat[, 2])
with(bndata, plot(jitter(y1), jitter(y2), col = "blue"))
}
