Abstract The early history of correspondence analysis is reviewed. It is shown that K. Pearsoncame very close to discovering correspondence analysis in 1906. That he did not actually discover it may be because he was not familiar with the singular value decomposition, which is the basic existence result in correspondence analysi

摘要:

Abstract Recently, VanZwet(1979) has discussed several conditions under which the celebrated mean‐median‐mode inequality holds. This note points out that VanZwet'sbasic condition and its variants have a simple interpretation in terms of a well‐known stochastic ordering. The results are slightly more general than VanZwet'sbecause the definition of unimodality used here (due to Khintchine) requires neither the existence of a density nor the uniqueness of t

摘要:

Abstract The problem considered here, is that of finding suitable conditions for dynamic economic systems that exclude the existence of observationally equivalent structures. Here observational equivalence refers to equality of distributions or first and second moments of a small finite sample from the observable process. It is shown, that under these conditions we may act as if the lagged endogenous variables are nonrandom exogenous variables, when global identifiability is investigate

摘要:

Abstract An informal discussion is given on performing an unconstrained maximization or solving non‐linear equations of statistics by iterative methods with the quadratic termination property. It is shown that if a miximized function, e.g. likelihood, is asymptotically quadratic, then for asymptotically efficient inference finitely many iterations are nee
