Professional Statisticians’ Forum

Professional Statisticians’ Forum (PSF) meetings enable professional statisticians to share professional experiences and discuss professional development. The meetings are intended for Chartered Statistician (CStat) and Graduate Statistician (GradStat) members, but all our members are welcome.

PSF events

PSF hosts virtual and face-to-face meetings. Events are held four times a year and typically run for 90 minutes with speakers and Q&A sessions. Many of the meetings are webinars and at least one is held during our conference.

Meeting papers and slides are available on our website at least a week ahead of an event.
We encourage you to pre-register for an event, though this will not be necessary for webinars.

Forum for recent GradStat awardees – the RSS and you

This meeting is primarily aimed at those who have recently been awarded GradStat status (in 2016 or 2017), to provide more information about what the Royal Statistical Society (RSS) has to offer and to provide an opportunity for networking with fellow GradStats and some CStats. Those awarded GradStat status prior to 2016 are also welcome to attend.

From 3:30 until 5:30 there will be presentations and discussion of:

- The RSS Professional Pathway and the route to Chartered status (CStat and CSci)
- Support provided along the pathway (including the GradStat mentoring scheme and mid-term review)
- Continuing Professional Development (CPD) – what’s expected in terms of doing and recording CPD
- Professional development events held by RSS (including the Professional Statisticians Forum and the Young Statisticians Section).
This will be followed by a reception which will enable networking with peers and some Chartered Statisticians.
This is a free-to-attend meeting. However, please register in advance of the meeting by contacting Ricky McGowan ( so we are aware of the numbers attending.

Missing data in clinical trials: making the best of what we haven’t got

Speaker: Michael O’Kelly (Principal Scientific Advisor, IQVIA)

Researchers in the last twenty years have come up with a snowstorm of ideas about how to interpret the results of clinical trials that have missing data. Michael O’Kelly summarises the landscape of ideas as he and his colleagues found it. A key change was the move from trying to “handle” missing data, to realising that missing data should be included in our understanding of clinical trial results. We can try to include missing data in our results by coarsening the outcome so as to include the missingness itself as part of that outcome; or by qualifying any estimate of treatment effect with sensitivity analyses; or by modelling some kind of counterfactual so as to attempt causal inference on a stratum of interest such as subjects who would have had no missing data. There are strong objections to each of these options, and the arguments continue. Michael will describe how in his own company, IQVIA, local Missing Data Superusers have improved the understanding of the issue of missing data, and also notes the strong co-operation in industry and academia in sharing methodologies for missing data. Current publicly available resources for statisticians will be summarised. Finally, Michael will talk about three key points: preventing missing data in clinical trials; how evidence from previous clinical trials can help give confidence in results when there is missing data; and the importance of clinical interpretability of results from trials with missing data.
