Medical statistics

...analysis of data and interpretation of results; this is typical of M249. It is relatively self-contained and should be reasonably easy to understand for someone with a good knowledge of introductory statistics. However, a few techniques and definitions are present in the extract without explanation. Mathematical/statistical content at the Open University is usually...

COVID-19: Making decisions based on flawed statistics

...analysis of this study is based on a simple regression (a statistical technique of estimating the relationship of one variable with another) of average daily infection rate against total reported cases per 1000 people, for 149 local authorities around the UK, on 8th April 2020. [Graph of total report cases and average daily infection rate for COVID-19] The analysis also...

Bayesian statistics

...data are observed, or information becomes available. Section 3 introduces the main ideas of the Bayesian inference process. The prior distribution summarises beliefs about the value of a parameter before data are observed. The likelihood function summarises information about a parameter contained in observed data and the posterior distribution represents what is known...

From intuition to inference: how experts inform Bayesian models

...analysis is often presented as beginning with data. In practice, this is rarely true. Before any data is collected, there are already expectations about what values are plausible, which outcomes seem unlikely, and what patterns might emerge. These expectations arise from previous studies, theoretical understanding, and practical experience. In many real-world problems,...
