The "Statistical Research Group" (Statistiska forskningsgruppen, SFG) provides statistical advice, primarily to research scientists, businesses and public authorities.

SFG is lead by lecturers and researchers at the Division of Mathematical Statistics at the Department of Mathematics at Stockholm University. The academic staff at Mathematical Statistics regards consultancy as natural part of their job.

SFG is a non-profit organization. The purpose is to encourage application of modern statistical methodology in science and industry, and to be complementary to the university education, by bringing students in contact with the diverse fields of application of modern statistics.

To some extent, SFG may also arrange courses for users of statistics.

SFG is run by a board chaired by docent Gudrun Brattström , with prof. Rolf Sundberg as vice-chairman.

Jan-Olov Persson is administrative leader of SFG.

Orders

SFG gladly accepts major and minor orders within all fields of statistics. Most of our contracts are to do with planning and analysis of (scientific) investigations and experiments. We do not do data collecting, interviewing et cetera.

SFG accepts assignments within all areas of statistics, like biostatistics (clinical trials, epidemiology), chemometrics, public statistics (e.g survey sampling) and industrial statistics (e.g quality control). In terms of statistical methodology, assignments can involve for example linear regression, logistic regression, analysis of variance, analysis of contingency tables, planning of experiments, sampling, multivariate analysis or survival data analysis.

Major contracts in recent years include:

• Analysis of road quality measurements and planning of sampling for traffic flow statistics, for The Swedish National Road Authority (Vägverket)
• Statistical analysis of corrosion data on cars, for The Swedish Corrosion Institute.
• Probabilistic and statistical analysis of damping when splicing optical fibres (Ericsson).
• Design of quality control (Sandvik-Coromant).
• Analysis of connections between oil impurity and breakdown risk for military vehicles, for The Swedish Defence Materiel Administration (FMV).

Master's theses

An important aim for SFG is to let students take part in the work, for example by writing their Master's theses in connection a major assignment of ours. Participation in the consultancy (under senior guidance, of course) gives them valuable introduction to their future professional activity.

Rates

For minor orders, we charge per hour in accordance with a fixed tariff. For major orders, and for courses, prices are subject to negotiation.
