"I'm just assuming that there's a historical regularity in the effect of the economy on how people vote, and I'm trying, through the use of econometrics, to estimate what that regularity is, and to use it to make a prediction".
The historical regularity of political-economic crises, which in recent times are occurring with greater frequency, is one such observation.
Ponzi schemes have at least three historical regularities: –They arise and grow in "hot market" moments.
In this respect, Ansoff himself had distinguished future uncertainty into an uncertainty which preserves a certain continuity compared with the past and therefore enables observers to estimate historical regularities, and an uncertainty which, on the contrary, is characterized by discontinuities and can become a threat or an opportunity.
Time-series forecasting uses historical empirical regularities, guided by a theoretical understanding of economic processes, to make future projections.
The main difference between sense I, on the one hand, and sense II and III on the other, is that whereas the practical and theoretical sciences of nature explain the occurrence of events by appealing to empirical regularities, the historical sciences explain actions by ascribing reasons to agents.
An important technique for extracting useful information, such as regularities, from usually historical data, is called as association rule mining.
We can utilize this regularity to improve the strong historical earthquake locations with large error originally, and even find a new candidate zone of a missed strong historical earthquake (Wang et al. 2004a, 2010; Wang 2007, 2011).
Thus, although it is logically possible to have complex inflectional morphology that is highly regular (frequently classified as agglutination), in practice, coarticulation, historical sound change, and other phonological/articulatory processes often subvert this regularity and lead to more idiosyncratic mappings [35] [37].
March 7, 1846 Århus, Denmark November 5, 1896 Copenhagen, Denmark Karl Verner, in full Karl Adolf Verner (born March 7 , 1846 Århus, Den. died Nov. 5, 1896, Copenhagen) linguist and formulator of Verner's law, which provided convincing evidence of the regularity of sound change in the historical development of languages.
Ecology, however, is a historical discipline and history is driven by both regularities (deriving from norms) and irregularities, or contingencies, which occur when norms are broken.
