peculiar for <strong>the</strong> foundations <strong>of</strong> physics but remote from experiment.Advisable here are efficient phenomenal models without specialclaims to fundamentalism. Accord<strong>in</strong>g to <strong>the</strong> pr<strong>in</strong>ciple <strong>of</strong> equal stability<strong>of</strong> all <strong>the</strong> elements <strong>of</strong> an applied <strong>in</strong>vestigation, <strong>in</strong>troduction <strong>of</strong>complicated ma<strong>the</strong>matics should be considered guardedly. I concludeby quot<strong>in</strong>g Wiener (1966 from Russian), hardly an opponent <strong>of</strong>ma<strong>the</strong>matization:Advancement <strong>of</strong> ma<strong>the</strong>matical physics caused sociologists to bejealous <strong>of</strong> <strong>the</strong> power <strong>of</strong> its methods but was hardly accompanied by<strong>the</strong>ir dist<strong>in</strong>ct underst<strong>and</strong><strong>in</strong>g <strong>of</strong> <strong>the</strong> <strong>in</strong>tellectual sources <strong>of</strong> that power.[...] Some backward nations borrowed Western clo<strong>the</strong>s <strong>and</strong>parliamentary forms lack<strong>in</strong>g personality <strong>and</strong> national dist<strong>in</strong>ctivemarks, vaguely believ<strong>in</strong>g as though <strong>the</strong>se magic garments <strong>and</strong>ceremonies will at once br<strong>in</strong>g <strong>the</strong>m nearer to modern culture <strong>and</strong>technology, − so also economists began to dress <strong>the</strong>ir very <strong>in</strong>exactideas <strong>in</strong> rigorous formulas <strong>of</strong> <strong>in</strong>tegral <strong>and</strong> differential calculuses. [...]However difficult is <strong>the</strong> selection <strong>of</strong> reliable data <strong>in</strong> physics, it is muchmore difficult to collect vast economic or sociological <strong>in</strong>formationconsist<strong>in</strong>g <strong>of</strong> numerous series <strong>of</strong> homogeneous data. [...] Under <strong>the</strong>secircumstances, it is hopeless to secure too precise def<strong>in</strong>itions <strong>of</strong>magnitudes brought <strong>in</strong>to play. To attribute to such magnitudes,<strong>in</strong>determ<strong>in</strong>ate <strong>in</strong> <strong>the</strong>ir very essence, some special precision is useless.Whatever is <strong>the</strong> excuse, application <strong>of</strong> precise formulas to <strong>the</strong>se to<strong>of</strong>reely determ<strong>in</strong>ed magnitudes is noth<strong>in</strong>g but a deception, a va<strong>in</strong> waste<strong>of</strong> time.Notes1. Both r<strong>and</strong>omization <strong>and</strong> <strong>the</strong> Monte Carlo method are mentioned by Prokhorov(1999) <strong>and</strong> Dodge (2003). Tutubal<strong>in</strong>, who had sided with Alimov, later applied <strong>the</strong>Monte Carlo method <strong>in</strong> a jo<strong>in</strong>t contribution (Tutubal<strong>in</strong> et al 2009, p. 189). O. S.2. Concern<strong>in</strong>g <strong>the</strong> <strong>the</strong>ory <strong>of</strong> probability <strong>the</strong> author was likely wrong, see Tutubal<strong>in</strong>[i, § 4.2], who [i, § 4.5] also remarked that for natural science <strong>the</strong> significance <strong>of</strong> <strong>the</strong>LLN only consisted <strong>in</strong> reflect<strong>in</strong>g <strong>the</strong> experimental fact <strong>of</strong> <strong>the</strong> stability <strong>of</strong> <strong>the</strong> mean.The author’s next sentence had to do with <strong>the</strong> application <strong>of</strong> <strong>the</strong> LLN to statistics, bu<strong>the</strong> only stated what that <strong>the</strong>orem did not achieve.Concern<strong>in</strong>g <strong>the</strong> CLT I quote Kolmogorov (1956, p. 269): Even now, it is difficultto overestimate [its] importance. O. S.3. In spite <strong>of</strong> numerous efforts made, <strong>the</strong> Mises approach rema<strong>in</strong>s actuallyquestionable, see end <strong>of</strong> [vi]. O. S.4. It is worthwhile to quote ano<strong>the</strong>r def<strong>in</strong>ition (Kolmogorov & Prokhorov1974/1977, p. 721):[Ma<strong>the</strong>matical statistics is] <strong>the</strong> branch <strong>of</strong> ma<strong>the</strong>matics devoted to <strong>the</strong>ma<strong>the</strong>matical methods for <strong>the</strong> systematization, analysis <strong>and</strong> use <strong>of</strong> statistical data for<strong>the</strong> draw<strong>in</strong>g <strong>of</strong> scientific <strong>and</strong> practical <strong>in</strong>ferences. O. S.5. See <strong>the</strong> Introduction to [v]. O. S.6. I illustrate pr<strong>in</strong>cipal <strong>and</strong> secondary magnitudes (§ 2.6) by Kolmogorov’sreason<strong>in</strong>g. Frequency µ/n tends to probability p, <strong>and</strong> <strong>the</strong> probability P(|µ/n − p| < ε) isa secondary magnitude which <strong>in</strong> turn should be measured as well. O. S.7. This statement is not altoge<strong>the</strong>r correct. See Wilks (1962, Chapter 11) <strong>and</strong>Walsh (1962) who discuss non-parametric estimation <strong>and</strong> order statisticsrespectively. O. S.8. Perhaps Kolmogorov (1963). O. S.132
