Chi-Squared Distribution Parameter Approximation
Abstract
A quick and effective method for determining from three frequency decibles the mean of a chi square distribution and an associated linear transform has been presented. The original purpose of the calculations was to allow creation of suitably distributed OTHR frequencies to be obtained, but the general principles used are applicable in other areas either in whole or in part. Errors have been estimated and have been shown to be greatest for small values of the mean, e.g. possibly as high as 20 per cent of the mean, although in practice errors of less than 10 per cent for the central 80 per cent of the distribution can be expected. For most common values encountered in other modelling, errors of less than 2 per cent of the mean can be expected.
