The New Zealand National Policy Statement for Freshwater Management 2020 sets several targets for freshwater quality, six of which are measurements of rivers; others relate to lakes. Each regional council is required to monitor freshwater quality and to respond as prescribed in order to meet the targets. One target of particular public interest  is based on four criteria determined from recent  E. coli readings, and concerns the health risk of swimming in a river. However, the inherent…

Does calculation of the 95th percentile of microbiological results offer any advantage over percentage exceedence in determining compliance with bathing water quality standards?

This study set out to determine whether draft WHO guidance is likely to suggest a calculated 95th percentile method, rather than percentage exceedence, in assessing compliance of bathing waters with microbiological standards, an appropriate development.

Consequences of dichotomization

Only in certain cases, for instance, in estimating a value of the cumulative distribution function and when the assumed model is very different from the true model, can the use of dichotomized outcomes be considered a reasonable approach.

Autonomous system for rapid field quantification of Escherichia coli in surface waters

The purpose of this work is to present and evaluate the performance of a novel Automatic Lab‐in‐vial Escherichia coli Remote Tracking technology based on an automated real‐time defined substrate

Comparison of Quantile Estimators in Normal Sampling

Ten nonparametric quantile estimators are compared with respect to small-sample performance characteristics including bias and mean squared error. The estimators considered are all linear functions

Fitting linear regression models to censored data by least squares and maximum likelihood methods

Several approaches have been suggested for fitting linear regression models to censored data. These include Cox's propor­tional hazard models based on quasi-likelihoods. Methods of fitting based on

Statistical control of hygienic quality of bathing water

General guidelines for bacterial control, their statistical background and practical application are presented and the evaluation and application of a specific programme for control of Staphylococcus aureus are presented.

Assessment of recent reductions in E. coli and sediment in rivers of the Manawatū-Whanganui Region

    Examine why the data was rounded and if possible, avoid rounding
