| dbo:abstract |
Probability distribution fitting or simply distribution fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon.The aim of distribution fitting is to predict the probability or to forecast the frequency of occurrence of the magnitude of the phenomenon in a certain interval. There are many probability distributions (see list of probability distributions) of which some can be fitted more closely to the observed frequency of the data than others, depending on the characteristics of the phenomenon and of the distribution. The distribution giving a close fit is supposed to lead to good predictions.In distribution fitting, therefore, one needs to select a distribution that suits the data well. (en) In de statistiek spreekt men van aanpassing als de parameter(s) geschat worden van de kansverdeling die zo goed mogelijk past bij een reeks waarnemingen. De mogelijke kansverdelingen behoren tot een geparametriseerde klasse en op basis van de waarnemingen wordt de parameter of worden de parameters geschat, waarbij verschillende criteria voor goed passen kunnen worden gehanteerd. Men zal een aangepaste verdeling bepalen als met deze verdeling meerdere kansuitspraken gedaan moeten worden. In de hydrologie, bijvoorbeeld, is het van belang de kans op een hoge rivierafvoer die eens per zoveel jaar voorkomt, te voorspellen. Hiervoor kan een aangepaste kansverdeling worden gebruikt en toegepast bij het ontwerp van verdedigingswerken tegen overstroming. (nl) |
