A Monte Carlo Study of the Robustness and Power Associated with Selected Tests of Variance Equality when Distributions are Non-Normal and Dissimilar in Form

Description: When selecting a method for testing variance equality, a researcher should select a method which is robust to distribution non-normality and dissimilarity. The method should also possess sufficient power to ascertain departures from the equal variance hypothesis. This Monte Carlo study examined the robustness and power of five tests of variance equality under specific conditions. The tests examined included one procedure proposed by O'Brien (1978), two by O'Brien (1979), and two by Conover, Jo… more

An Investigation into the Determinants of Performance in the Dual-Fund Industry in the United States from Inception Through 1973

Description: This research is a systematic, in depth empirical test of the strong form of the efficient market hypothesis (EMH) using the dual-fund industry as the research subject. Unlike most strong-form EMH research, this study deals with a small, homogeneous sector of the investment company industry with a comparable origin date. To obtain homogeneity of the research subjects, the sample size is necessarily small (7), thus, making it difficult to find statistically significant results. In general, portf… more

An Empirical Investigation of Marascuilo's Ú₀ Test with Unequal Sample Sizes and Small Samples

Description: The study seeks to determine the effect upon the Marascuilo Ú₀ statistic of violating the small sample assumption. The study employed a Monte Carlo simulation technique to vary the degree of sample size and unequal sample sizes within experiments to determine the effect of such conditions, Twenty-two simulations, with 1200 trials each, were used. The following conclusion appeared to be appropriate: The Marascuilo Ú₀ statistic should not be used with small sample sizes and it is recommended that… more

Heart Rate as an Index of Student Cognitive Activity in a Classroom

Description: The purpose of this study was to test the Lacey hypothesis of cardiac behavior patterns for possible use as a measure of attentiveness in a classroom where experimental variables were not controlled. Lacey's hypothesis predicted cardiac deceleration with instances of information-intake and cardiac acceleration with instances of information-processing. Third grade students in a self-contained classroom were telemetrically monitored for heart rate during reading group activities. Based on cardiac… more

The Effects of Selection Risk on Sex Discrimination in Employment Decisions

Description: Effects of selection risk on sex discrimination in hiring were investigated. Ninety-six male and female educational administration graduate students rated ficticious resumes on suitability for hiring for the female-oriented position of secondary school teacher. Sex and selection risk level were varied, with sex of rater as an assigned factor. Analysis of variance yielded significant main effects for sex (p < .01) and selection risk level (p < .05). All ratings were lower in high selection-risk … more

Robustness of the One-Sample Kolmogorov Test to Sampling from a Finite Discrete Population

Description: One of the most useful and best known goodness of fit test is the Kolmogorov one-sample test. The assumptions for the Kolmogorov (one-sample test) test are: 1. A random sample; 2. A continuous random variable; 3. F(x) is a completely specified hypothesized cumulative distribution function. The Kolmogorov one-sample test has a wide range of applications. Knowing the effect fromusing the test when an assumption is not met is of practical importance. The purpose of this research is to analyze the … more

Do Predictions of Professional Business Economists Conform to the Rational Expectations Hypothesis?: Tests on a Set of Survey Data

Description: A set of forecast survey data is analyzed in this paper for properties consistent with the Rational Expectations Hypothesis. Standard statistical tests for "rational expectations" are employed utilizing consensus forecasts generated by an interest rate newsletter. Four selected variables (Fed Funds rate, M1 rate of growth, rate of change in CPI, and real GNP growth rate) are analyzed over multiple time horizons. Results tend to reject "rational expectations" for most variables and time horizons… more

Bank Loans as a Financial Discipline: A Direct Agency Cost of Equity Perspective

Description: In a 2004 study, Harvey, Lin and Roper argue that debt makers with a commitment to monitoring can create value for outside shareholders whenever information asymmetry and agency costs are pronounced. I investigate Harvey, Lin and Roper's claim for bank loans by empirically testing the effect of information asymmetry and direct agency costs on the abnormal returns of the borrowers' stock around the announcement of bank loans. I divide my study into two main sections. The first section tests whet… more

Is Modernization the Engine of Political Instability?: A Pooled Cross-Sectional Time-Series Test of Causality

Description: Traditional studies of the modernization-instability thesis have neglected the simultaneous influence of time and place on the relationship between modernization (social mobilization and political participation) and political instability, and the possible causal linkage between the two concepts. Empirical support for modernization-instability hypothesis will be obtained if and only if there is a strong positive correlation between modernization and political instability and the former causes th… more

Effects of Amount of Postshift Training on Resistance to Extinction

Description: The investigation sought to examine resistance to extinction (Rn) as a function of previous experience with downward shifts in reward magnitude. It was suggested that previous research conducted within the framework of the Spence-Amsel frustration hypothesis and the sequential hypothesis failed to administer sufficient postshift trials to adequately establish the relationships that may exist. Under one condition, four groups of rats received twenty extinction trials following forty postshift tr… more
