transnormalizationとは 意味・読み方・使い方

名詞

transnormalization (uncountable)

1. (mathematics かつ sciences) The transformation of raw data such that the resulting cumulative distribution is normal.
   • 1977, Proceedings of the 7th Technical Exchange Conference, El Paso, Texas, 30 November-3 December 1976:

     This procedure is termed transnormalization. Using variables that are transnormalized is a necessary, but not sufficient, condition for the joint distribution to be multi-normal. However, tests to date have shown that joint normality is a good assumption whenever the variables have been selected by nature, as opposed to having been selected artificially by man. Predictors selected by man, such as time of day, are included in the TRP equation as "marginal" variables.

   • 1977, Raymond L. Joiner, Separation of Mixed Data Sets Into Homogeneous Sets:

     ... such transnormalization.

   • 1978, Meteorological and Geoastrophysical Abstracts"

     The three main procedures that comprise this multivariate transnormalized method are transnormalization, correlation, and regression conditional probability. The transnormalization process (a nonlinear process) transforms the observed or raw data into the standard normal variable with the same cumulative climatological probability as the raw predictor. Transnormalization ensures normal distribution of the predictor.
