Marketing research using single-item indicators in structural equation models

Should researchers use single indicators, best indicators, or multiple indicators in structural equation models?

BACKGROUND Structural equation modeling developed as a statistical melding of path analysis and factor analysis that obscured a fundamental tension between a factor preference for multiple indicators and path modeling's openness to fewer indicators. DISCUSSION Multiple indicators hamper theory by unnecessarily restricting the number of modeled latents. Using the few best indicators - possibly...

Component Analysis for Structural Equation Models with Concomitant Indicators

A new approach to structural equation modelling based on so-called Extended Redundancy Analysis has been recently proposed in literature, enhanced with the added characteristic of generalizing Redundancy Analysis and ReducedRank Regression models for more than two blocks. However, in presence of direct effects linking exogenous and endogenous variables, the latent composite scores are estimated...

Using Structural Equation and Item Response Models to Assess Relationship between Latent Traits

We deepen the two main approaches to the problem of measurement error in social sciences, the Structural Equation Models (SEM) and the Item Response Theory Models (IRM), comparing two different estimation procedures. The One-step procedure (related to SEM) requires that researcher specifies a complete model of both measurement aspects (single link between the latent variable and its indicators)...

Pricing Models in Marketing Research

Pricing a product is one of the most important decisions an organization can make. Marketing research has developed several different approaches to price optimization. They include direct methods such as estimation of willingness to pay, indirect methods such as Gabor-Granger and van Westendorp techniques, and product/price mix methods such as various discrete choice models. All of them are wid...
