CONDITIONALITY OF AIR TEMPERATURE BY TIDAL CHANGES OF GRAVITY ^{[№ 6 ' 2005]}
With the help of he determined methods the matrix of research is under construction with the average on hour sections tidal changes of gravity and researched parameters. Statistical methods define qualitative and quantitative conditionality of parameters. Multinomial and harmonious forecasting models are resulted.

CONDITIONALITY OF DECADES AND DAYS OF TOTAL TEMPERATURE TRANSITION THROUGH 0, 5, 10 GRADE (SPRING, AUTUMN) BY SOLAR ACTIVITY ^{[№ 7 ' 2004]}
Factorial and correlative analyses were carried out in order to define qualitative conditions of research parameters. Qualitative conditions specification was made by means of spectral analysis which helped to distinguish harmonics with peak amplitude for each parameter. Final models for research parameters definition according to Volf number were made by means of Brundon's method with step-by-step parameter-argument elimination.

ALGORITHM OF MINIMIZATION OF THE QUANTITY OF PARAMETERS OF RESEARCH IN GEO ECOLOGY. ^{[№ 4 ' 2004]}
Minimization of number of parameters of research for polyvalent object is suggested on the basis of factorial and regression analysis. Space of parameters converges greatly due to choice of base parameters, without worsening of exact characteristics of the description of polyvalent object.
