Factors of local recurrence and organ preservation with transoral laser microsurgery in laryngeal carcinomas; CHAID decision-tree analysis.
2018
BACKGROUND Indications of transoral laser microsurgery (TLM) are conditioned by the risk of local relapse. OBJECTIVE To evaluate prognostic factors of local relapse and local control with TLM (LC-TLM). METHODS Local relapse and LC-TLM were evaluated in 1119 patients. Logistic regression and CHAID decision tree analysis were performed. RESULTS Local relapse correlated to previous radiotherapy failure (8.45, CI 95%: 2.64-27.03; P < .001), paraglottic involvement (2.42, CI: 1.41-4.15; P = .001), anterior commissure involvement (2.12, CI: 1.43-3.14; P < .001), grade of differentiation (1.74, CI: 1.18-2.57; P = .005), and alcohol consumption (1.4, CI: 0.99-1.98; P = .057). Local relapse tended t…
Urine Testing During Treatntent Predicts Cocaine Abstinence
2010
The objective of this study was to analyze the influence of the variables that predict cocaine abstinence on an outpatient program for the treatment of addiction to this substance. Participants were 80 patients (85% men and 15% women) selected at random from those receiving treatment at a Spanish health service outpatient unit. For detecting the predictor variables the authors carried out a chi-square automatic interaction detection (CHAID) analysis. Logistic regression analysis and discriminant analysis were performed to estimate the probability of abstinence according to/using the predictor variables detected by CHAID analysis. Abstinence rate after six months of treatment was 37.5%. The …
Determinantes del comportamiento de queja y su importancia en la segmentación de clientes insatisfechos
2008
ResumenEsta investigación de carácter exploratorio aborda el proceso de formación del comportamiento de queja utilizando el proceso de segmentación de clientes. Consideramos que dicho comportamiento agrupa dos tipos de respuestas a la insatisfacción: las respuestas de queja y las respuestas privadas. Nuestro objetivo es conocer la capacidad que tiene la intensidad de la insatisfacción y otras variables relevantes de la literatura en la discriminación de segmentos de consumidores, con el propósito de estudiar sus comportamientos y características. La metodología de análisis CHAID ha permitido segmentar la muestra en diferentes grupos identificando los principales antecedentes de ambos tipos …
Emotional and Altruistic Values as Drivers for a Loyalty-Based Segmentation in Retailing: An Approach to Postrecession Spanish Apparel Consumers
2016
ABSTRACTResearch on consumer behavior has supported the usefulness of the experiential approach to explain shopping and consumption in the context of retailing. The present article aims at assessing the soundness of an extended experiential value concept for segmenting apparel retail customers in terms of their loyalty toward the store. A CHAID algorithm based on a sample of postrecession Spanish apparel retail customers has identified three segments of customers with differentiated levels of loyalty toward the store: play (emotional value) and ethics (altruistic value) are the most relevant variables for defining these segments.

Customer segmentation based on commitment and ICT use
2009
PurposeThe purpose of this paper is to determine and characterize groups of retail customers, based on their perception of commitment to the retailer and the degree of use of its technological equipment.Design/methodology/approachA CHAID algorithm is performed and differences between the resulting segments are tested through the analysis of variance.FindingsFour segments are obtained that differ significantly in commitment to the retailer and level of use of the store's information and communication technology (ICT) facilities, as well as in other variables related to the retailer‐consumer relationship. In particular, customer segments differ in their use of retailers' payment facilities.Pr…
