A new numerical scheme for the CIR process
Nikolaos Halidias · Monte Carlo Methods and Applications · 2015
Abstract In this paper we generalize an explicit numerical scheme for the CIR process that we have proposed before. The advantage of the new proposed scheme is that preserves positivity and is well posed for a (little bit) broader set of parameters among the positivity preserving schemes. The order of convergence is at least logarithmic in general and for a smaller set of parameters is at least 1/4.
