Application of Stochastics to Scientific Research, Problems - Misconceptins - Risks     pdf     HR     EN 499
Summary: Scientific research in the field of forestry is mainly stochastics, requiring the use od stochastic models, i.e. the method of inferential statistics. Hardly any theories are available, though in some fields they occured and were studied (Raucher 1980). The paper deals with the problem encountered by the researchers dealing with living organisms, particularly with their activities. Such work (applicative) is compared with the so coled fundamental research resulting in theories. Stochastics, deterministics, empirical, i.e. explanatora models are accordingly discussed. This part of the studies was aroused by Raucher (1987) and a discussion within the IUFRO Group S6.02. The second part of the paper is a short mommentary on the misinterpretations about statistics as an aid in making decisions. Statistics is frequently regarded as indispensable, overpowering, objectiv and accurate. In many cases the results yielding obvious conclusions are encumbering with unnecessary statistical "evidence". It sometimes happens that an evident hypothesis is rejected if refused by statistical test. It is frequently forgotten that the inferencial statistics is based on a great number of conditions which have not always been fulfilled. On the other hand, the conditions are sometimes aproached too rigorously. The autor thinks that the use of statistics by being aware that "we are not doing quite correctly " is less hazardous than the use of the correct procedure which we do not understand (here is the emphasis on the problems of statistical packages). The autor points out the idea (Warren 1986) that our conclusions are always subjective. Another misunderstanding is the opinion that statistics can prove opinion and hypotheses. The third par illustrates inadequate use of mathematical statistics with example which are in the authors opinon still presentin literature, though quite some time has passed since the first warnings known to the author (Utts 1986, Warren 1987). Significantly, with computers playing a major part in it, the same analysis of the same data will not always give the same results.
