  • Bias Approximations for Complex Estimators

    Open AccessZarrel V Lambert, Albert R Wildt et al.ARTICLEEducational and Psychological…1991

    In applied research designed to address conceptual as well as program and policy formulation issues, it is often important to assess the bias present in estimators of association and prediction stemming from the use of multivariate analytical procedures. However, the theoretic sampling distributions of these estimators are often unknown in applied research contexts because of their complexity and the inability to satisfy highly restrictive assump…

  • Approximating Confidence Intervals for Factor Loadings

    Zarrel V Lambert, Albert R Wildt et al.ARTICLEMultivariate Behavioral Research1991

    Practical theoretic means for assessing the sampling variability of loadings estimated by exploratory factor analytic procedures have not been readily available in the absence of restrictive distributional assumptions. It has been necessary for researchers to interpret these point estimates (loadings) through the use of arbitrary rules-of-thumb. Under these conditions, loading interpretations may be problematic. A method is presented for exploiti…

  • Assessing Sampling Variation Relative to Number-of-Factors Criteria

    Open AccessZarrel V Lambert, Albert R Wildt et al.ARTICLEEducational and Psychological…1990

    Employment of the bootstrap method to approximate the sampling variation of eigenvalues is explicated, and its usefulness is amplified by an illustration in conjunction with two commonly used number-of-factors criteria: eigenvalues larger than one and the scree test. Confidence intervals for eigenvalues are approximated for sample correlation matrices that have ones and squared multiple correlation coefficients on the diagonals. The results demon…

  • Approximate Confidence Intervals for Estimates of Redundancy Between Sets of Variables

    Zarrel V Lambert, Albert R Wildt et al.ARTICLEMultivariate Behavioral Research1989

    Use of redundancy analysis would be enhanced by having available a procedure that (a) evaluates the statistical significance of the estimated proportion of variance in the criterion variable set extracted by a given predictor variate, Ry i (2), as well as by all predictor variates combined, R(y 2), and (b) is lenient with respect to assumptions about the distributions of redundancy estimates. A previous testing method leaves in doubt the assessme…

  • Predispositions Toward Generic Drug Acceptance

    Zarrel V Lambert, Paul L Doering et al.ARTICLEJournal of Consumer Research1980Cited by: 3

    This study examined the predispositions of persons, particularly the elderly poor, toward substituting chemically equivalent generic drugs for more expensive brand name products prescribed by their physicians. The findings suggest that these persons are not prone to choose generic substitutions for brand name drugs

  • Generalizability of Cognitive Differentiation across Product and Social Domains

    Open AccessRichard M Durand, Zarrel V LambertARTICLEPsychological Reports1976

    This study examined the degree to which cognitive differentiation—the capacity to view objects, persons, and events in a multidimensional manner—was generalized across two very different consumer products and interpersonal relations. Substantial generalizability would hold important implications for understanding choice processes. The observed correlations between differentiation scores for the three domains were weak although statistically signi…

  • Dogmatism and Exposure to Political Candidates

    Open AccessRichard M Durand, Zarrel V LambertARTICLEPsychological Reports1975

    Formation and change of political as well as other beliefs are a function of a person's exposure to information which is subject partially to his control. He may actively seek or avoid additional information, particularly information that might be discrepant with preconceived opinions. The hypothesis was that Ss with high scores on dogmatism were less willing than Ss with low scores to attend speeches of presidential primary candidates whose view…
