    Searching for connections between biological and physico-chemical characteristics of Rybinsk reservoir ecosystem. Part 1. Criteria of connection nonrandomness
    Computer Research and Modeling, 2013, v. 5, no. 1, pp. 83-105

    Based on contents of phytoplankton pigments, fluorescence samples and some physico-chemical characteristics of the Rybinsk reservoir waters, searching for connections between biological and physicalchemical characteristics is working out. The standard methods of statistical analysis (correlation, regression), methods of description of connection between qualitative classes of characteristics, based on deviation of the studied characteristics distribution from independent distribution, are studied. A method of searching for boundaries of quality classes by criterion of maximum connection coefficient is offered.

    Searching for connections between biological and physico-chemical characteristics of Rybinsk reservoir ecosystem. Part 3. Calculation of the boundaries of water quality classes
    Computer Research and Modeling, 2013, v. 5, no. 3, pp. 451-471

    Approbation of calculation of borders of water quality classes for the purpose of ecological diagnosis and standardization by data of the Rybinsk reservoir is carried out. For bioindication indicators of phytoplankton fluorescence and the contents of pigments of phytoplankton are used. Chesnokov's importance coefficient proved to be the most preferred measure of connection for analyzing the effects of environmental factors on indicators. The factors important for environmental condition are identified. Comparison of borders between quality classes “valid” and “invalid” of factors values and boundaries of the classifications of water quality.

    Searching for connections between biological and physico-chemical characteristics of Rybinsk reservoir ecosystem. Part 2. Determination analysis
    Computer Research and Modeling, 2013, v. 5, no. 2, pp. 271-292

    Based on contents of phytoplankton pigments, fluorescence samples and some physico-chemical characteristics of the Rybinsk reservoir waters, searching for connections between biological and physicalchemical characteristics is working out. The methods of describing of connections between qualitative classes of characteristics, based on forecast of quality values of one characteristics by quality values of another one, are studied. The borders of quality classes of studied characteristics are found.
