Gauss-Laguerre using statmod
...y used. Again, the internal
integrate function yields:
> integrate(ff, lower=target, upper=Inf)
0.7580801 with absolute error < 7.2e-05
Now, my understanding of the change of variable needed for
Gauss-Laguerre in this instance is simple, x = y_i + target. As such,
the integration should be
truePos <- function(target, m, mu, sigma, sigma_i, Q = 30){
gq <- gauss.quad(Q, kind="laguerre")
nodes <- gq$nodes
whts <- gq$weights
y <- pnorm((nodes + target - m)/sigma_i) * dnorm(nodes + target, mu,
sigma)
sum(y * exp(nodes)* whts)
}
> truePos(target = 200,...
