Introduction----------------This code simulates commodity spot prices using the Clewlow and Strickland one factor daily spot model using a Monte Carlo approach. The derived stochastic differential equations (SDEs) are solved using several finite difference schemes.The paper detailing the...

The Hardy Weinberg equilibrium is a fundamental law in genetic.This function was deeply rewrited.If a locus is biallelic the function use the exact Hardy Weinberg test (similar to Fisher exact test) analyzing all possible tables. If you download TERNPLOT functions (ID:2299) the function plots a...

Simulates the wall effect in a gaseous thermal neutron detector with a gaseous neutron converter (He-3) using the Monte Carlo method. Based on the gap thickness (in m) and the partial pressure of helium-3 (in bar), this program computes the fraction of events that suffers to some extent from the...

As a coursework, we are required to price a double barriers knock-in binary put option. We used finite difference method in 24 ways and multinomial lattice in 12 ways. We also implemented analytic and Markov chain method. At the end, we compared these four methods and Monte Carlo method.In this...
