The next RSS Environmental Statistics Section meeting is on
environmental time series and will be held in Edinburgh.
ENVIRONMENTAL STATISTICS SECTION
Thursday 24 February 2005, 2.00pm to 5.00pm
International Centre for Mathematical Sciences, 14 India Street,
Edinburgh EH3 6EZ
PETER GUTTORP (University of Washington, Seattle)
Time series of proportions
Environmental data frequently occur as proportions. We develop an
algebra for proportions, which allows a flexible tool for modelling
proportions in space and time. The theory is illustrated on examples
from air quality, ecology, and water quality.
LAURENCE CARVALHO (CEH Edinburgh) and CLAIRE FERGUSON (University of
Glasgow)
Unravelling Climate Impacts on Water Quality - a case study of Loch
Leven
Loch Leven, the largest shallow lake in the UK, has been monitored
since 1968. A marked trend in temperature, with consequent changes in
seasonality of lake biology and water quality, is explored using both
transfer function models and non-parametric additive models.
SUJIT SAHU (University of Southampton)
Spatio-temporal modeling of fine particulate matter
Short-term exposure to high concentrations of fine atmospheric
particulate matter (PM2.5) can lead to long-term health effects. A
random effects model incorporating urban/rural differences with
population density weighting is proposed to predict PM2.5 levels. A full
Bayesian implementation gives predictions in time and space using data
from 3 US states.
Further details of the meeting and abstracts of the talks will be made
available on the envstat web-page
