It is well-known that the classic exploratory factor analysis (EFA) of data with more observations than variables has several types of indeterminacy. We study the factor indeterminacy and show some new aspects of this problem by considering EFA as a specific data matrix decomposition. We adopt a new approach to the EFA estimation and achieve a new characterization of the factor indeterminacy pr...

We consider the use of intervention data for eliminating the underdetermination in statistical modelling, and for guiding extensions of the statistical models. The leading example is factor analysis, a major statistical tool in the social sciences. We first relate indeterminacy in factor analysis to the problem of underdetermination. Then we draw a parallel between factor analysis models and Ba...

This paper provides a solution to the stability puzzle (Evans and McGough [11]): indeterminacy almost always implies expectational unstability in reduced-form real business cycle (RBC) models. After relaxing the restrictions on the magnitude of capital externalities with CobbDouglas technology, we nd regions for joint indeterminacy and E-stability in the following cases that i) the felicity fun...

In this paper, we study the occurrence of local indeterminacy in two-sector monetary economies. In order to capture the credit market imperfections and the liquidity services of money, we consider a general MIUF model with two alternative timings in monetary payments: the Cash-In-Advance timing, in which the cash available to buy goods is money in the consumers’ hands after they leave the bond ...

A LINGUISTIC PREFATORY NOTE The word “bestimmt,” in German, is fundamentally underdetermined. It can mean “festgelegt,” i.e., “determined,” “resolute”; or it can mean “gewiß,” i.e., “certain,” “sure”; or it can mean “genau,” i.e., “precise,” “specified,” “explicit.” When Werner Heisenberg chose to call his famous principle the “Unbestimmtheitsrelation,” his was a stroke of genius: thanks to the...

This paper presents a method to eliminate inherent indeterminacy of permutation and dilation existing in the classical independent component analysis (ICA). The method incorporates additional requirements or a priori information as constraints in the ICA contrast function. We illustrate how this approach sorts independent components (ICs) according to some statistic and normalizes the demixing ...

This paper deals with the problem of merging descriptions of approximate spatial location specified at different levels of granularity. We distinguish between the roughness of an approximation at a given level of granularity and the indeterminacy that arises when approximations are transformed from one level of granularity to another. Indeterminacy arises in particular when an approximation is ...

Understanding how indeterminacy is different from uncertainty crucial to posthumanism and has major implications for reconfiguring curriculum. Uncertainty do with epistemology, about not knowing whether a state of affairs or not; instance, one would know something here there, now then. Indeterminacy, however, ontological eschews the idea individually existing determinate entities, proposing ins...
