In Louis' 82 formula for the information of partially observed data, the last term is the gradient-squared of the partial data likelihood. It doesn't have to be calculated because it's 0 at the MLE, but it's coded here for debugging purposes.
BDPOloglikeGradSqr.CTMC_PO_many(partialDat, L, m, beta, n.fft = 1024)CTMC_PO_many.
lambda at which to calculate information; usually MLE.
mu at which to calculate information; usually MLE.
known constant defining nu via nu=beta*lambda.
deprecated unused.
