The Hit & Miss Sample Mean Model investigates Monte Carlo integration techniques. The user is able to input a 1D integrand and finite integration limits and specify the number of trials and the number of separate runs. The simulation allows the user to study the dependence of the uncertainty/error on the number of trials.

The Monte Carlo Integration wiht Importance Sampling Model implements the sample mean and importance sampling techniques of Monte Carlo integration. The user can input a 1D integrand and finite integration limits and specify the required Monte Carlo technique or techniques.
The importance sampling technique requires the user to input a normalized probability distribution p(x) that matches the integrand in its main features, and an associated transformation law x(y) that converts a uniform y in [0,1) into an x sampled according to p(x). The simulation does perform a check on the normalization of p(x), but the result may be inaccurate for distributions defined over a very large interval or those with strange behavior. The number of trials and the number of separate runs can be chosen by the user.
