\title{Bivariate Power Distribution}
\usage{
pbivpower(x1, x2, p1 = 1, p2 = 1, theta = 0)

sbivpower(x1, x2, p1 = 1, p2 = 1, theta = 0)

dbivpower(x1, x2, p1 = 1, p2 = 1, theta = 0)

rbivpower(n, p1 = 1, p2 = 1, theta = 0)
}
\arguments{
\item{x1, x2}{Values in the support.}

\item{p1, p2}{Positive shape parameters.}

\item{theta}{Association parameter, \eqn{0 \le \theta \le 1}.}

\item{n}{Number of random observations.}
}
\value{
Numeric vector or two-column matrix (\code{rbivpower}).
}
\description{
Distribution function, survival function, density, and random generation for
the bivariate power distribution:
\deqn{F(x_1,x_2) = x_1^{p_1 + \theta \log x_2}\,
  x_2^{p_2},\quad 0 \le x_1,x_2 \le p_2,\; p_1,p_2 > 0,\; 0 \le \theta \le 1.}
}
\examples{
pbivpower(0.4, 0.5, p1 = 2, p2 = 2, theta = 0.3)
set.seed(7); head(rbivpower(30, p1 = 2, p2 = 2, theta = 0.2))
