Course objectives
The course focuses on basic statistical methods and models. In the beginning, basic concepts of mathematical statistics are studied. Then a regression analysis is studied, as the first the linear regression model, followed by generalized linear models. It is a course where the practical applications in other fields is immediate and very common. At the end of this course the student will be able to understand the principles of mathematical statistics and data analysis, how to use these results for specific models, understand the relationships between different types of models, interpret their results.
Syllabus
  • 1.Exploratory data analysis. Number characteristics of data sample, diagnostics graphs - boxplot,N-P plot, Q-Q plot, P-P plot, histogram.
  • 2.Basic terms of mathematical statistics: random sampling, basic statistics and their properties, testing of hypotheses. The empirical distribution function and survival function.
  • 3.Basics of regression and correlation analysis: the term of regression and correlation, correlation coefficient, multiple correlation coefficient, partial correlation coefficient.
  • 4.Linear regression model: its definition, estimates of unknown parameters, hypothesis testing, verification of the model. Most important applications: two-sided t-test, analysis of variance, standard regression models - linear regression, polynomial and trigonometric regression. Regression models for correlated data.
  • 5.Analysis of variance. Construction of the model and testing the hypothesis about sample means equality. Sample variance equality tests. Multiple comparisons methods.
  • 6.Generalized linear models: description of model components (a linker function, linear predictor, the distribution of exponential type for dependent variables). The most important applications: gamma regression, regression models for the alternative (binary) and binomial data, batch response models, models for nominal and ordinal data, poisson regression, log-linear models.
  • 7.Modeling of dependence between qualitative variables - contingency tables. Testing the independence and homogeneity, four-array contingency tabulars.

Teaching methods
Lectures: theoretical explanation with practical examples, Excercises: computer excercises focused on acquirement of basic concepts, solving simple tasks in R language
Assessment methods
Lectures and exercises. Active work in exercises. One computer test within the semester. The test consists of 2-3 examples and is for 30 points. 50% of points is needed to pass fulfilling requirements. Examination consists of two parts: written and oral. Written part consists of 8 theoretical questions, each for 10 points. The final result is corrected by the oral part. Final grade: A: 72 - 80 points B: 63 - 71 points C: 54 - 62 points D: 45 - 53 points E: 36 - 44 points F: 0 - 35 points
