September Meetup - Expert elicitation and unit testing in R

After the summer break, Sheffield R group is back with a couple of great talks to kick off the new season.

Our beginner's talk this month, presented by Alison Parton, is:

Can you trust the humble statistician? An intro to unit testing in R

"You've slaved away converting the awesome methods you've concocted into R code. It runs without any nasty red errors so you've not missed an end bracket, but are they all really in the right place? I'll be telling beginners what I've learnt after dipping my toes into the world of unit testing in R, and (hopefully) getting the veterans to assist in my quest for reliable code."

SHELF: an R package for expert elicitation

For our expert talk we welcome Professor Jeremy Oakley who will introduce SHELF, an R package containing tools to support the Sheffield Elicitation Framework (SHELF). This is a toolkit for eliciting probability distributions from experts, translating an expert's judgements about the characteristics of a distribution for a parameter of interest into a range of parametric distributions and providing visual and summary feedback. SHELF also provides methods for interactive plotting and elicitation, weighting for multiple expert elicitation and a graphical interface for the roulette elicitation method.

Hope to see you there!

National Biodiversity Network data hack kickoff event

We are delighted to announce the first Hack event for the SheffieldR Users Group! This event aims to bring together R users and learners of all levels for a hands on session with some real world open data. We will be working with the National Biodiversity Network (NBN) dataset, which records sightings of different species along with their location taken from numerous wildlife surveys. This event is supported by the Sheffield Wildlife Trust, and we will be sharing our outputs with them as we go.

This is the kickoff of the hack that will introduce the data set and set the scene for the hack events. The hack will take place over three consecutive evenings. You are welcome to attend as many or as few sessions as you wish - so don't worry if you can't commit to all three at this stage.

All are welcome - there will be a mix of experienced R users as well as beginners, and no knowledge of biodiversity is required. An introductory session will be held on Feb 23rd at the February SheffieldR Users Group meeting at the Red Deer - you can sign up to this and any future SheffieldR events at our meetup site (http://www.meetup.com/SheffieldR-Sheffield-R-Users-Group/).

Hack Planning

This is an initial planning afternoon.. a zeroth meeting to shake down any important details left for organising future events. It is also an excuse to go to a pub on a Sunday afternoon.

Please note that the space itself is not going to be reserved as turnout is expected to be low, particularly given the late notice. If you wish to attend, please sign up on the opentechcalendar event page just in case it turns out this will be more popular than the organiser expects.
