SF2930 Regression Analysis 7.5 credits


This course offers an introduction to modern methods of regression analysis with applications.   Regression analysis is a statistical technique for investigating and modelling the relationship between a variable of interests,  the response,  and a set of related predictor variables. Regression techniques are of high practical importance and their extensive use is a hallmark of modern statistical applications. Successful application of regression analysis demands appropriate acquaintance with underlying theory and handling of real world problems. The overall goal of the course meeting the demand is thus twofold:  to acquaint students with the statistical methodology of the regression modelling and to develop advanced practical skills that are necessary for applying regression techniques to a  real-world data analysis problem.

Content and learning outcomes

Course contents *

The course begins with simple and multiple linear regression models for which fitting, parametric and model inference as well as prediction will be explained.  Topics covered are least squares (LS) and generalised LS, the Gauss-Markov theorem,  geometry of least squares and orthogonal projections.  A special attention is paid to the diagnostic strategies which are key components of good model fitting.  Further topics include transformations and weightings to correct model inadequacies, the multicollinearity issue, variable subset  selection and model building techniques.  Later in the course, some general strategies for regression modelling will be presented with a particular focus on the generalized linear models (GLM) using the examples with binary and count response variables.

As the high-dimensional data, order of magnitude larger than those that the classic regression theory is designed for,  are nowadays a rule rather than an exception in computer-age practice  (examples include  information technology,  finance,  genetics and astrophysics,  to name just a few),   regression methodologies  which allow to cope with the high dimensionality are presented.  The emphasis is placed on methods of controlling the regression fit by  regularization (Ridge, Lasso and Elastic-Net),  as well as methods using derived input directions  (Principal Components regression and Partial Least Squares) that allow to tamp down statistical variability in high-dimensional estimation and prediction problems. 

A number of statistical learning procedures with the focus on computer-based algorithms is presented from a regression perspective. 

Computer-aided project work with a variety of datasets forms an essential learning activity.

Intended learning outcomes *

To pass the course, the student should be able to do the following:

  • know the sampling  properties of point estimators used in linear regression models as well as  principles  and assumptions behind different estimation techniques applied
  • list and understand the assumptions behind standard parametric and model inference in the  linear  regression models
  • assess the fit of a regression model to data and know  how to identify and diagnose potential problems with a linear regression model
  • design and implement the strategy  to correct model inadequacies,  and report on  the expected accuracy which can be achieved with the suggested model;  
  • identify and develop  regression modelling strategies suitable  for large sample as well as for high-dimensional settings
  • explain how the multiple linear regression can be generalized to handle a response variable that is categorical or a count variable 
  • use resampling algorithms, in particular,  the bootstrap and  cross-validation, for estimation of the model predictive accuracy. Understand the needs for and  benefits of resampling methods in regression modelling and assessment  
  • critically evaluate regression models in a real-world applications,  and present the analysis and conclusions in a written report
  • read current research papers and understand the issues raised by current research

To receive the highest grade, the student should in addition be able to do the following:

  • combine several methods and models in order to gain better results
