This paper describes computational experiments with an algorithm for control-rounding any series of linked tables such as typically occur in official statistics, for the purpose of confidentiality protection of the individual contributors to the tables. The resulting tables consist only of multiples of the specified rounding base, are additive, and have(More)
This paper describes a geographically intelligent approach to disclosure control for protecting flexibly aggregated census data. Increased analytical power has stimulated user demand for more detailed information for smaller geographical areas and customized boundaries. Consequently it is vital that improved methods of statistical disclosure control are(More)
The plant pathogen Sclerotinia sclerotiorum can cause serious losses on lettuce crops worldwide and as for most other susceptible crops, control relies on the application of fungicides, which target airborne ascospores. However, the efficacy of this approach depends on accurate timing of these sprays, which could be improved by an understanding of the(More)
