We have had decades of successful experience in statistical consulting, theoretical and mathematical modelling.
Our members have more than 25 years of combined experience in university teaching, supervision and mentoring.
Our extensive and broad expertise in statistical data analysis and mathematical modelling is supported by more than 350 papers (with more than 7000 citations) in total in refereed journals, conference proceedings and symposia in science and engineering, environmental sciences and engineering, medical research and clinical trials, epidemiology and population health, healthy ageing, ecology and habitat.
Within the recent years, our members have had 21 invited talks at international conferences, meetings, and academic institutions.
We prepared numerous project reports for our clients in a wide range of areas including environmental engineering and management, social and natural sciences, psychology, population health, clinical and medical research and development, education and business research, operations research and management.
We have exceptional expertise in mentoring, supervision and coordination of major collaborative projects. In addition, our members were principal supervisors of 14 PhD students, 5 Masters, 13 Honours and 12 undergraduate research students.
Our specific expertise in consulting, data analysis, simulation and modelling includes the following:
Statistical methods and approaches:
- graphic and descriptive techniques, correlations, t-tests, ANOVA, Cronbach’s alpha, proportions, etc.;
- continuous and categorical data;
- survey/questionnaire data analysis;
- sample size determination and power calculation;
- principal component analysis and canonical correlations;
survival analysis, extended and stratified Cox regressions, recurrent events, competing risks, and episode splitting; - generalised linear models;
- random (mixed) effects models;
- Generalised Estimating Equations (GEE);
- cluster analysis and multilevel modelling;
- growth curve models, Poisson and negative binomial regressions with clustering;
- multivariate analysis, MANOVA, seemingly unrelated regressions, etc.;
- regressions with measurement errors and constraints;
- ROC-curve approaches for marker development, including ROC regression controlling for covariates;
- model averaging approaches and relative variable importance;
- Structural Equation Modelling (SEM) and generalised SEM;
- multilevel factor analyses;
- analysis of spatially correlated data for environmental, ecological, epidemiological, economical and political applications;
- time series and autocorrelated data;
- financial statistics and econometrics models and applications;
- high-performance computing and data analyses (Linux platform);
- multidimensional data modelling (including netCDF files);
- data management and manipulation of particularly large databases.
Operations Research:
- modelling of complex business and service-providing systems;
- discrete event simulation;
- simulation and optimisation of the available resources;
- optimisation of complex management decisions and decision-making processes, including such areas as supply chain operation, health system applications, queueing and scheduling network problems, etc.
Other modelling methodologies:
- design and construction of surveys and questionnaire instruments in a variety of areas;
- qualitative data analysis and coding of unstructured data;
- geographic information system (GIS) for environmental, ecological and climate change applications;
- environmental and atmospheric modelling, sustainable development and renewable energy, transport and industry emissions;
- design and modelling in engineering, physics, optics, photonics, acoustics, hydrodynamics, nanotechnology and fabrication.
We also have extensive experience and advanced expertise in the following statistical and other software packages: S-Plus, R, R on Linux, Stata (including the GLLAMM package), SPSS, Minitab, ExtendSim (for operations research simulations), NVivo (for qualitative analysis and data coding), Matlab, Mathematica, COMSOL, etc.
