Monte Carlo simulations of the Freedman-Clauser experiment are used to testthe generic wave function collapse model of Quantum Mechanics, a localrealistic model, and a dynamical state reduction model of wave functioncollapse. The simulated results are compared to the actual results of theexperiment which confirmed the quantum mechanical calculation for ninedifferent relative angles between the two polarization analyzers. For eachsimulation $5\times10^7$ total simulated photon pairs were generated at eachrelative angle. The generic wave function collapse model closely followed thegeneral shape of the theoretical calculation but differed from the calculatedvalues by 2.5% to 3.3% for angles less than or equal to $\pi/8$ and differed by15.0% to 52.5% for angles greater than or equal to $3\pi/8$. The localrealistic model did not replicate the experimental results but was generallywithin 1% of a classical calculation for all analyzer angles. A dynamical statereduction/collapse model, approximated by using a "smeared" polarization,yielded values within 1% of the quantum mechanical calculation and provides anindependent estimate of the correlation length used in these models of $r_c =(1.04 \pm 0.14)\times 10^{-5}$ cm.
