Objective

The students should get an overview of teh basic properties of probability to be able to deal with simple practical problems in probability. They should get familiar with the basic statistical methods used for interval estimates, testing statistical hypotheses, and linear model.

Knowledge

Student will be able to solve simple practical probability problems and to use basic statistical methods from the fields of interval estimates, testing parametric and non-parametric statistical hypotheses, and linear models.

Syllabus

1. Continuous and discrete random variable (vector), probability function, density function. Probability.

2. Properties of probability. Cumulative distribution and its properties.

3. Relationships between probability, density and cumulative distributions. Marginal random vector. Independent random variables.

4. Numeric characteristics of random variables: mean and variance, standard deviation, variation coefficient, modus, quantiles. Rules of calculation mean and variance.

5. Numeric characteristics of random vectors: covariance, correlation coefficient, covariance and correlation matrices.

6. Some discrete distributions - discrete uniform, alternative, binomial, Poisson, hypergeometric - definition, using.

7. Some continuous distributions - continuous uniform, exponential, normal, multivariate normal - definition applications.

8. Chi-square distribution, Student´s distribution - definition, using. Random sampling, sample statistics.

9. Distribution of sample statistics. Point estimation of distribution parameters, desirable properties of an estimator.

10. Confidence interval for distribution parameters.

11. Fundamentals of hypothesis testing. Tests of hypotheses for normal distribution parameters. Asymptotic test on the alternative distribution parameter.

12. Goodness-of-fit tests. Chi - square test. Basics of regression analysis.
