A high-performance Rust implementation of the Turnbull non-parametric maximum likelihood estimator for interval-censored survival data

A common need in biostatistics is to estimate survival curves, but particular difficulty arises when observations are interval censored, i.e. the time of event is not observed exactly, but is known only to fall within a particular interval. In this setting, the Turnbull estimator [1]… »

Extracting TOTP keys from a proprietary Android 2FA app

This is an analysis of an early 2010s proprietary Android-based two-factor authentication (2FA) application for a particular cloud service provider – à la Okta, or Microsoft Authenticator. This particular cloud service has been publicly criticised for not supporting industry standard 2FA algorithms such as time-based… »

A high-performance Rust implementation of interval-censored Cox regression

Cox proportional hazards models are commonly used in biostatistics for the modelling of time-to-event data, such as mortality or disease progression. A difficulty in applying Cox models arises when observations are interval censored, i.e. the time of event is not observed exactly, but is known… »

What drugs are dosed other than in milligrams?

Notes

This discussion was prepared by examining items on the Australian Pharmaceutical Benefits Scheme (PBS) General Schedule, Repatriation PBS and Section 100 Highly Specialised Drugs (Public Hospital) programs, as at February 2023. I do not warrant that this will remain accurate in the future. Non-PBS… »

Simulating plausible ballot paper preferences from STV count sheets

Introduction

When analysing single transferable vote (STV) elections, we often desire a record of the preferences lodged by voters, so that voting patterns can be analysed in detail, or to see how changes in voters' preferences or in the rules of the count might impact… »
