In most practical cases, the underlying dimensionality of Bermudan options is high and the numerical methods for solving partial differential equations as satisfied by the price process become inapplicable. In the absence of analytical formula a popular approach is to solve the Bermudan option pricing problem approximately using dynamic programming via estimation of the so-called continuation value function. In this paper we develop a nearest neighbor estimator based technique which gives biased estimators for the true option price. We provide algorithms for calculating lower and upper biased estimators which can be used to construct valid confidence intervals. The computation of lower biased estimator is straightforward and relies on suboptimal exercise policy generated using the nearest neighbor estimate of the continuation value function. The upper biased estimator is similarly obtained using likelihood ratio weighted nearest neighbors. We analyze the convergence properties of mean square error of the lower biased estimator. We develop order of magnitude relationship between the simulation parameters and computational budget in an asymptotic regime as the computational budget increases to infinity. <\/jats:p>","DOI":"10.1142\/s0219198915400022","type":"journal-article","created":{"date-parts":[[2014,12,4]],"date-time":"2014-12-04T21:20:39Z","timestamp":1417728039000},"page":"1540002","source":"Crossref","is-referenced-by-count":3,"title":["Nearest Neighbor Based Estimation Technique for Pricing Bermudan Options"],"prefix":"10.1142","volume":"17","author":[{"given":"Ankush","family":"Agarwal","sequence":"first","affiliation":[{"name":"STCS, Tata Institute of Fundamental Research, Homi Bhabha Road, Mumbai, Maharashtra 400005, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandeep","family":"Juneja","sequence":"additional","affiliation":[{"name":"STCS, Tata Institute of Fundamental Research, Homi Bhabha Road, Mumbai, Maharashtra 400005, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2015,3,2]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1007\/s00780-010-0132-x"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1214\/105051605000000485"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1086\/260062"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4612-1718-3"},{"key":"rf6","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-1889(97)00029-8"},{"key":"rf7","doi-asserted-by":"crossref","first-page":"35","DOI":"10.21314\/JCF.2004.117","volume":"21","author":"Broadie M.","year":"2004","journal-title":"J.
