EFFICIENT METHOD FOR DETERMINATION OF MODE VALUES OF RANDOM GEOPHYSICAL VALUES Russian patent published in 2016 - IPC G06F17/17 

FIELD: data processing.

SUBSTANCE: invention relates to methods of determining mode of values of geophysical value W - wind velocity, height of sea, air temperature. Geophysical value W is repeatedly measured, measurement results form a time series of data W(t) and, using a series measurement data W(t), an empirical probabilistic function availability F(W), then for determined analytical function availability F_ap(W), which is extrapolated beyond maximum value of measurement data W_M to value specified probabilistic mode, from which unknown value of a secure geophysical value is determined. Analytical approximation F_ap(W) is made in form of a polynomial degree of n, coefficients of which are determined using a known method in logarithmic coordinates for functions of availability and linear coordinates for geophysical value W. Lower W_lo and upper W_hi boundary region of constructing approximation [W_lo, W_hi] and degree of n is chosen so that value of logarithm of approximating function F_ap(W_M), taken at point of maximum value of measurement data W_M, that is larger than corresponding values of empirical function F(W_M) on value not exceeding error Δ for F(W_M), which is determined by measurement data.

EFFECT: method provides higher reliability of obtained estimates of operating values.
