Dear All,
The next seminar of the South Wales local group of the RSS takes place on
Wednesday 3rd November at 5:00pm in Room M/2.06 at the School of Mathematics,
Senghennydd Road, Cardiff (next door to the Sherman Theatre).
Tea and Coffee will be served from 4:30pm in Room M/1.04.
The speaker is Dr Robert Newcombe (Cardiff University) on:
Confidence intervals for proportions and related quantities
Many journals relating to healthcare and other fields now require confidence
intervals rather than p-values as the main expression of uncertainty due to
limited sample size. When the quantities of interest are proportions or derived
measures, poor methods are still widely used. This talk will summarise work on
the development and evaluation of improved interval estimates for a variety of
such measures and related graphical methods, leading up to recent work on U/mn,
a generalisation of the Mann-Whitney statistic which is equivalent to the area
under the ROC curve and Somers' D. For many of these computations, highly
user-friendly Excel resources have been developed which are freely available via
the web to the wider research community.
The December seminar takes place on Thursday 9th December at 5:00pm in the
Epidemiology and Public Health Seminar Room at the University Hospital of Wales,
Heath Park, Cardiff. Tea and Coffee will be served in the foyer from 4:30pm.
The speaker is Professor Andy Grieve (Pfizer) on:
Statistics and Its Place in the Evolution of Medicine as an Evidence-Based
Science
The famous controlled trial by James Lind in 1747 in which he investigated the
effect of oranges and lemons on scurvy is well-known and is often seen as
standing alone. In fact relatively recent research has shown that far from being
an isolated event, Lind's trial was but one example of many attempts to
introduce quantitative measurement into medicine in the 18th century. In this
talk I will look at other examples from the 18th century and look at the
parallels that there are with modern evidence-based medicine.
All are welcome.
Best wishes
Rebecca
