The research group of Prof Mikko J. Sillanpää is developing new computationally efficient and practical statistical methods and their applications in biology, medicine and other fields. Bayesian analysis and data analytic methods using hierarchical models and Markov Chain Monte Carlo sampling methods are preferred in the group. In many of the problems we are working with, important parts of the solution are formed by the efficient handling of the big-data, use of data analytic tools having close connections to the machine learning theory, and algorithmic view of computational methods. Specifically, the present research interest address statistical variable selection methods having sparsity-inducing mechanism. From the Bayesian viewpoint, this mechanism can be called as a shrinkage prior and it can be called as a penalty or regularization function from the classic statistical viewpoint. Examples of these are different LASSO-related priors.

From biology point of view, the group studies different problems in QTL mapping and genomic prediction. Especially, the properties and use of Bayesian multi-locus models (i.e., Bayesian whole-genome regression or Bayesian alphabets) in identifying genetic determinants (including epistasis) and prediction of individual's genetic value (merit / risk) to the quantitative, qualitative and function-valued human, plant and animal traits based on genome-wide sets of molecular markers. Also the group have a specific interest towards use of Bayesian mixed models such as Bayesian G-BLUP and other mixed models in estimating genomic parameters, genomic heritability, or genomic breeding values.

Newer interests are different variance and precision matrix inference methods having sparsity-inducing mechanism. The conditional independence structure between variables can be inferred by studying which of the precision matrix elements are zero and non-zero. The inferring conditional independence structure between variables is same as estimating topology of the graph or estimating network structure. Thus, we are developing new statistical sparsity-inducing estimation tools for variance and precision matrices as well as estimating sparse network structures from data sets. Biologically this is closely connected to different problems in systems biology.

BAPS / Windows software for Bayesian analysis of population structure

winzip-file containing executable program, dll-files, manual, and test data set can be found in BAPS

The population structure estimation work that we initially started as methodological project to correct for unobserved counfounders in association analysis (Sillanpää et al. 2001; Ripatti et al. 2001) later on culminated in development of BAPS (Corander et al. 2003, 2004). Our new development of population structure estimation work is represented by Gasbarra et al. (2007a,b) where the unknown relatedness structure (pedigree and geneflow) are simultaneously estimated and different degrees of relationships are allowed among the study individuals.

BAPS versions are implemented using MATLAB and are then converted to C-language, where only executable programs are distributed. For user information and installation details, see the manual. Details of the method are presented in the papers :
