The main urgent difficulties dealing with humanity this present day - over-population, strength shortages, weather swap, soil erosion, species extinctions, the chance of epidemic ailment, the specter of struggle which can break all of the hard-won profits of civilization, or even the hot fibrillations of the inventory industry - are all ecological or have a wide ecological part.

This problem is quite different from the one discussed up to now in tenms of both the reason for under-estimation and the applications (those concemed with instantaneous rather than accumulated maxima). Consequently, the discussion here is brief, recognising that the problem deserves a full, separate investigation. ) measure the degree to which the maximum max(1) is under-estimated due to thinning by the factor f For positive data, 0sR(f)<1. This analysis system, of uilizing all the possible thinned records obtainable for a given thinning factor f, yields a distribution of ratios which is representative of the range of ratios to be expected.
