Application of count data models
Reichmanová, Barbora ; Hampel,, David (oponent) ; Hübnerová, Zuzana (vedoucí práce)
When analysing the data on emergence of plants in a row of a given length, we should consider both the probability of a seed to grow successfully and a random number of seeds sown. That is why this thesis is adressing the random sums, where number of independent identically distributed summands is random number independent of the summands. The first part of the thesis focuses on the theoretical basis, where the term random sum is introduced together with various properties, numerical and functional characteristics outlining the distribution. Afterwards the method of maximum likelihood estimation is discussed, followed by generalized linear models. Moreover, the quasilikelihood method is described briefly. Throughout this part, the theory is illustrated with examples related to the initial problem. The application on real data is discussed in the last chapter.
