The Impact of Using Truncated Data to Estimate Variance.

Abstract

This report examines the effect of truncation of data on the estimation of variance in fix estimation. The methodology used in QUICKFIX is examined in detail. The effect of different truncation parameters and different numbers of LOBs are tabulated. Under the assumption that truncation is centered about the true mean, a formula for correcting for truncation is presented in Appendix I. Appendix II is missing and can be obtained by contracting MARC directly. Keywords: Computations; Standard deviation.
