\title{Closed-Form BLT of Reversed Residual Lives for the FGM Distribution}
\usage{
blt_reversed_fgm(s1, s2, theta = 0)
}
\arguments{
\item{s1, s2}{Positive Laplace parameters.}

\item{theta}{FGM association parameter, \eqn{|\theta| \le 1}.}
}
\value{
Scalar numeric; the joint bivariate Laplace transform.
}
\description{
Computes the bivariate Laplace transform of the FGM distribution in closed
form (Jayalekshmi and Rajesh, Example 1):
\deqn{L_X(s_1,s_2) = \frac{(1-e^{-s_1})(1-e^{-s_2})}{s_1 s_2}
  + \theta \Phi(s_1,s_2)}
where \eqn{\Phi} captures the dependence correction.
}
\examples{
blt_reversed_fgm(s1 = 1, s2 = 1, theta = 0.5)
blt_reversed_fgm(s1 = 2, s2 = 0.5, theta = -0.3)
