Double integration - Gauss Quadrature
...length(nodes)){
sum <- (sum + ab_weights[i]*f(ab_nodes[i]))}
return(sum)
}
gauss_legendre(function(y) {
sapply(y, function(y) {
gauss_legendre(function(x) x*y, 0, 1, nodes, weights)$value
})
}, 0, 1, nodes, weights)
Can anybody tell me where the problem lies?
Thank you for your help!

R's integrate function
...05/1.005))*dbeta(y,x/(0.005/1.005),(1-x)/(0.005/1.005))*(1-y)^z,0,1,423)$value
})
},0,1,423)$value
but I receive an error message saying that the maximum number of
subdivisions is reached. If I choose a smaller z it works fine. Does
anyone know what the problem is?
Thank you very much in advance,
