Previous publications on hierarchical linear modeling (HLM) have provided guidance on how to perform the analysis, yet there is relatively little information on two questions that arise even before analysis: Does HLM apply to one’s data and research question? And if it does apply, how does one choose between HLM and other methods sometimes used in these circumstances, including multiple regress...

In a hierarchical or fixed-order regression analysis, the independent variables are entered into the regression equation in a prespecified order. Such an analysis is often performed when the extra amount of variance accounted for in a dependent variable by a specific independent variable is the main focus of interest (e.g., Cohen & Cohen, 1983). For example, in the area of reading achievement, ...

Customer needs in service settings are idiosyncratic. Responding to these unique requires frontline employees be creative. Little research looks at the drivers of employee creativity. We aim fill that void by assessing two potential key creativity drivers, control mechanisms and management orientations. collected data from their managers used multilevel mediation modeling, configurational model...

These lecture notes present some basic intuitions underlying structural equations modeling (SEM). If you find this technique useful in your research, I suggest that you take a semester-long course on SEM and/or hierarchical linear model (HLM). It turns out that SEM and HLM are essentially the same technique but some things are easier to implement in one versus the other so disciplines tend to f...

This study of the flow of online discussions examined how previous messages affected the current message along five dimensions: (1) evaluations (agreement, disagreement, or unresponsive actions); (2) knowledge content (contribution, repetition, or null content); (3) social cues (positive, negative, or none); (4) personal information (number of visits); and (5) elicitation (eliciting response or...

Face-to-face interactions are a crucial part of services. However, research that investigates the dynamics of service encounters is still rare. In this study we used a theoretical framework that aligned the concept of interpersonal complementarity with Mehrabian and Russell’s (1974) three-dimensional model of affect. We hypothesized that there are positive relationships between employees’ and c...

This paper presents analytical approach for modeling of 11-level cascade multilevel STATCOM connected to power system for voltage regulation applications. A technique based on energy equivalence is proposed for computation of equivalent capacitance which represents true value of variable structure of capacitances connected in individual H-bridges. The necessity of equivalent capacitor is an ess...

The Pratt index is a useful and practical strategy for day-today researchers when ordering predictors in a multiple regression analysis. The purposes of this study are to introduce and demonstrate the use of the Pratt index to assess the relative importance of predictors for a random intercept multilevel model.
