Abstract: According to x2 testification theory of population distribution hypothesis, a method of estimating population parameters through searching for the minimum value point of x0 variable was presented. It was shown that population parameters could be estimated for any one-dimensional or two-dimensional random variable by this method, only if its probability density function exists

Key words: fatigue, fatigue load, parameter estimation
