# To testify the hypotheses about the role of characteristic X_{zmw}
in activity F prediction, Decision Making Theory and Zadeh’s fuzzy logic are used.

# 1) For each sequence S_{n} with known activity F_{n} the
characteristic X_{zmw} is calculated:

# 2) The __simple regression__ is optimized based on the all {X_{zmw}(S_{n});
F_{n}} pairs:

# 3) Totally the following __22 conditions__ {q _{i}}_{1}£
i£ 22 of the regression
analysis __applicability__ are tested: linear, sign, rank correlations between X_{zmw}(S_{n})
and F_{n }values; the equality of distributions of these values, and others.

# 4) The __significance level__ a _{i} is estimated at which the __condition__ q _{i} __is met__.
