Evaluating the use of exploratory factor analysis in psychological research

by Leandre R. Fabrigar, Duane T. Wegener, Robert C. MacCallum, Erin J. Strahan - PSYCHOLOGICAL METHODS , 1999
"... Despite the widespread use of exploratory factor analysis in psychological research, researchers often make questionable decisions when conducting these analyses. This article reviews the major design and analytical decisions that must be made when conducting a factor analysis and notes that each of ..."

Approximation by Superpositions of a Sigmoidal Function

by G. Cybenko , 1989
"... In this paper we demonstrate that finite linear combinations of compositions of a fixed, univariate function and a set ofaffine functionals can uniformly approximate any continuous function of n real variables with support in the unit hypercube; only mild conditions are imposed on the univariate fun ..."

function. Our results settle an open question about representability in the class of single bidden layer neural networks. In particular, we show that arbitrary decision regions can be arbitrarily well approximated by continuous feedforward neural networks with only a single internal, hidden layer and any

Choices, values and frames.

by Daniel Kahneman - American Psychologist, , 1984
"... Making decisions is like speaking prose-people do it all the time, knowingly or unknowingly. It is hardly surprising, then, that the topic of decision making is shared by many disciplines, from mathematics and statistics, through economics and political science, to sociology and psychology. The stu ..."

. The study of decisions addresses both normative and descriptive questions. The normative analysis is concerned with the nature of rationality and the logic of decision making. The descriptive analysis, in contrast, is concerned with people's beliefs and preferences as they are, not as they should be

Privacy-Preserving Data Mining

by Rakesh Agrawal , Ramakrishnan Srikant , 2000
"... A fruitful direction for future data mining research will be the development of techniques that incorporate privacy concerns. Specifically, we address the following question. Since the primary task in data mining is the development of models about aggregated data, can we develop accurate models with ..."

Making Fast Strategic Decisions in High-Velocity Environments

by Kathleen M. Eisenhardt - Academy of Management Journal , 1989
"... How do executive teams make rapid decisions in the high-velocity microcomputer industry? This inductive study of eight microcomputer firms led lo propositions exploring that question. Fast decision makers use more, not less, information than do slow decision makers. The former also develop more, not ..."

Investing for the long run when returns are predictable

by Nicholas Barberis - Journal of Finance , 2000
"... We examine how the evidence of predictability in asset returns affects optimal portfolio choice for investors with long horizons. Particular attention is paid to estimation risk, or uncertainty about the true values of model parameters. We find that even after incorporating parameter uncertainty, th ..."

ONE OF THE MORE STRIKING EMPIRICAL FINDINGS in recent financial research is the evidence of predictability in asset returns. 1 In this paper we examine the implications of this predictability for an investor seeking to make sensible portfolio allocation decisions

Learning Multiple-Question Decision Trees for Cold-Start Recommendation

by Mingxuan Sun, Ke Zhou, Fuxin Li, Guy Lebanon, Joonseok Lee, Hongyuan Zha
"... For cold-start recommendation, it is important to rapidly profile new users and generate a good initial set of recommendations through an interview process — users should be queried adaptively in a sequential fashion, and multiple items should be offered for opinion solicitation at each trial. In th ..."
Abstract - Cited by 5 (0 self) - Add to MetaCart
. In this work, we propose a novel algorithm that learns to conduct the interview process guided by a decision tree with multiple questions at each split. The splits, represented as sparse weight vectors, are learned through an L1-constrained optimization framework. The users are directed to child nodes

To parcel or not to parcel: Exploring the question, weighing the merits. Structural Equation Modeling

by Todd D. Little, William A. Cunningham, Golan Shahar, Keith F. Widaman , 2002
"... We examine the controversial practice of using parcels of items as manifest variables in structural equation modeling (SEM) procedures. After detailing arguments pro and con, we conclude that the unconsidered use of parcels is never warranted, while, at the same time, the considered use of parcels c ..."

cannot be dismissed out of hand. In large part, the decision to parcel or not depends on one’s philosophical stance regarding scientific inquiry (e.g., empiricist vs. pragmatist) and the substantive goal of a study (e.g., to understand the structure of a set of items or to examine the nature of a set

Attitudes towards Risk. Experimental Measurement in Rural India

by Hans P. Binswanger, Rekha Gaiki, K. G. Kshirsagar, Madhu Nath , 1978
"... Attitudes toward risk were measured in 240 households using two methods: an interview method eliciting certainty equivalents and an experimental gambling approach with real payoffs which, at their maximum, exceeded monthly incomes of unskilled laborers. The interview method is subject to interviewer ..."

to determine whether differences in behavior between farmers of different wealth levels are the consequence of different attitudes towards risk or of different constraint sets such as limitations on credit or on access to modern inputs. This question is of consid-erable policy importance because policy pre
