Statistical Analysis of Rounded Data: Measurement Errors vs Rounding Errors [PDF]

open access: yesJournal of Mathematical Sciences, 2018
Consider the measurements in which the discretization step is constant and without loss of generality is equal to 1. The measured value \(X\) is rounded to the closest integer \(X^*\) according to the rule \(X^*=[X+0.5]\) where \([x]\) is the integer part of \(x\). Measurements of the quantity \(\mu\) are considered as i.i.d. random samples \(X_1,\dots,

Symmetric and Asymmetric Rounding [PDF]

open access: yes, 2006
If rounded data are used in estimating moments and regression coefficients, the estimates are typically more or less biased. The purpose of the paper is to study the bias inducing effect of rounding, which is also seen when population moments instead of ...
