Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

行銷硏究 : Marketing research

In this innovative approach to the practice of social science, Charles Ragin explores the use of fuzzy sets to bridge the divide between quantitative and qualitative methods. Paradoxically, the fuzzy set is a powerful tool because it replaces an unwieldy, "fuzzy" instrument—the variable, which establishes only the positions of cases relative to each other, with a precise one—degree of membership in a well-defined set. Ragin argues that fuzzy sets allow a far richer dialogue between ideas and evidence in social research than previously possible. They let quantitative researchers abandon "homogenizing assumptions" about cases and causes, they extend diversity-oriented research strategies, and they provide a powerful connection between theory and data analysis. Most important, fuzzy sets can be carefully tailored to fit evolving theoretical concepts, sharpening quantitative tools with in-depth knowledge gained through qualitative, case-oriented inquiry. This book will revolutionize research methods not only in sociology, political science, and anthropology but in any field of inquiry dealing with complex patterns of causation.

Customer loyalty or repeat purchasing is critical for the survival and success of any store By focusing on online stores, this study investigates the repeat purchase intention of experienced online buyers based on means-end chain theory and prospect theory In the research model, both utilitarian value and hedonic value are hypothesised to affect repeat purchase intention positively Perceived risk is hypothesised to affect repeat purchase intention negatively and moderate the effects of utilitarian and hedonic values on repeat purchase intention Utilitarian value is proposed as a formative second-order construct formed by product offerings, product information, monetary savings and convenience Hedonic value is also proposed as a formative second-order construct formed by the six hedonic benefits that have been identified in prior research Data collected from 782 Yahoo!Kimo customers provide strong support for the research model The results indicate that both the utilitarian value and hedonic value are positively associated with buyers' repeat purchase intention A higher level of perceived risk reduces the effect of utilitarian value and increases the effect of hedonic value on repeat purchase intention Implications for theory and practice and suggestions for future research are provided

Understanding customers' repeat purchase intentions in B2C e-commerce: the roles of utilitarian value, hedonic value and perceived risk

Purpose – The purpose of this paper is to understand customers' repurchase intentions in online shopping. This study extends the technology acceptance model (TAM) by introducing e‐service quality dimensions, trust and enjoyment in the development of a theoretical model to study customers' repurchase intentions within the context of online shopping.Design/methodology/approach – Data collected from 360 PCHome online shopping customers provides strong support for the proposed research model. PLS (partial least squares, PLS‐Graph version 3.0) is used to analyse the measurement and structural models.Findings – The study shows that trust, perceived ease of use, perceived usefulness and enjoyment are significant positive predictors of customers' repurchase intentions.Research limitations/implications – The data are collected from a single online shopping store – the generalisation of the model and findings to other online stores requires additional research. Our findings imply that the five dimensions of e‐servi...

Determinants of customer repurchase intention in online shopping

Purpose – The aim of this study is to extend DeLone and McLean's IS success model by introducing justice – fair treatments received from the exchanging party – and trust into a theoretical model for studying customers' repurchase intentions in the context of online shopping.Design/methodology/approach – The research model was tested with data from 219 of PCHome's online shopping customers using a web survey. PLS (partial least squares) was used to analyze the measurement and structural models.Findings – Data collected from 219 valid respondents provided support for all but one hypotheses (with a p‐value of less than 0.05). The unsupported hypothesis regards the relationship between service quality and satisfaction (H4). The study shows that trust, net benefits, and satisfaction are significant positive predictors of customers' repurchase intentions toward online shopping. Information quality, system quality, trust, and net benefits, are significant determinants of customer satisfaction. Besides, online tr...

In justice we trust: Exploring knowledge-sharing continuance intentions in virtual communities of practice

Social networking sites (SNSs) are one of the Web 2.0's most utilized services, and the influential force of electronic word of mouth (eWOM) on SNSs deserves our unequivocal attention. This study aims to explore how users of SNSs adopt information embedded in eWOM reviews shared by other users. Using the stimulus-organism-response model and affect-as-information theory, we devised and tested a theoretical framework linking both a cognitive path and an affective path to approach eWOM adoption on SNSs. Two curiosity constructs—informational deprivation epistemic curiosity (D-EC) and interest-type epistemic curiosity (I-EC)—are regarded as moderators of the cognitive path and the affective path, respectively. Data collected from 445 respondents support all of our hypotheses. The results show that beyond the conventional cognitive path (cognitive stimuli and the credibility of eWOM), the affective path (affective stimuli and arousal) can also contribute to eWOM adoption. We also find that SNS users focus on d...
