LÉVY-BASED ERROR PREDICTION IN CIRCULAR SYSTEMATIC SAMPLING

open access: yesImage Analysis and Stereology, 2013
In the present paper, Lévy-based error prediction in circular systematic sampling is developed. A model-based statistical setting as in Hobolth and Jensen (2002) is used, but the assumption that the measurement function is Gaussian is relaxed.

CONDITIONS FOR EXACT CAVALIERI ESTIMATION

open access: yesImage Analysis and Stereology, 2014
Exact Cavalieri estimation amounts to zero variance estimation of an integral with systematic observations along a sampling axis. A sufficient condition is given, both in the continuous and the discrete cases, for exact Cavalieri sampling.
