Design a Monte Carlo experiment that studies the variation of the EM solutions around this numerical optimum.
When using nlm, the modes are obtained within a few iterations, depending on the starting points, and the intermediate values of the Newton-Raphson sequence.
Examine the performance of this algorithm in terms of acceptance probability when using a simulated sample with the same parameters as in Figure .
Deduce from the acceptance rate an estimator of the normalizing constant of f for each of the instrumental densities.
Derive an estimate of E[X|X>K] based on a sample from F.
Show that the sum of the weights ?i = f(Xi)/g(Xi) is only equal to n in expectation and deduce that the weights need to be renormalized .
Monte Carlo marginalization is a technique for calculating a marginal density when simulating from a joint density.
Deduce the regular and the self-normalized sequences of estimators of E[exp(X)].
Show that the bias due to the replacement of µ by x¯ n is of the order of a X2n term, which can thus be corrected directly in dn.
Show that Sigma=cov(matrix(rnorm(30),nrow=10)) defines a proper covariance matrix.
Show that the probability of acceptance in an Accept-Reject algorithm with upper bound M on the density ratio f /g is 1/M.
Compare the execution times of the two proposed implementations of the Accept-Reject algorithm, as well as alternatives simulating Nsim*Nprop proposals .
Show that the probability of acceptance is then and deduce that, to produce one normal random variable, this Accept-Reject algorithm requires .
