Abstract
In this paper, we present a novel method to estimate the parameters of a quadratic curve. We show that by grouping the data points and by estimating the so-called moments difference (MD) which are unbiased and consistent, the parameters of a quadratic curve can be estimated with higher accuracy than the existing methods
