Research Commentary---Too Big to Fail: Large Samples and the p-Value Problem
TLDR
This research commentary recommends a series of actions the researcher can take to mitigate the p-value problem in large samples and illustrates them with an example of over 300,000 camera sales on eBay.Abstract:
The Internet has provided IS researchers with the opportunity to conduct studies with extremely large samples, frequently well over 10,000 observations. There are many advantages to large samples, but researchers using statistical inference must be aware of the p-value problem associated with them. In very large samples, p-values go quickly to zero, and solely relying on p-values can lead the researcher to claim support for results of no practical significance. In a survey of large sample IS research, we found that a significant number of papers rely on a low p-value and the sign of a regression coefficient alone to support their hypotheses. This research commentary recommends a series of actions the researcher can take to mitigate the p-value problem in large samples and illustrates them with an example of over 300,000 camera sales on eBay. We believe that addressing the p-value problem will increase the credibility of large sample IS research as well as provide more insights for readers.read more

A framework for the study of positive deviance in organizations
TL;DR: In this article, the authors synthesize existing definitions and approaches to the organizational study of positive deviance, integrate them into a coherent conceptual framework, and offer methodological advice and illustrations.

Evaluating Trade Areas Using Social Media Data with a Calibrated Huff Model
TL;DR: This case study divided Beijing into regular grid cells and extracted activity centers for each social media user and found that sets obtained by aggregating user activity centers have a better delimitating effect than sets obtained without aggregation.

Large-scale semi-automated acoustic monitoring allows to detect temporal decline of bush-crickets
Alienor Jeliazkov,Yves Bas,Christian Kerbiriou,Jean-François Julien,Caterina Penone,Isabelle Le Viol +5 more
TL;DR: In this paper, the authors used an acoustic region-wide citizen-monitoring program of Orthoptera, conducted along roads, to assess the relevance of automatic species recognition methods to detect temporal trends while taking into account spatial and seasonal patterns of two orthoptera species activity at a large scale.

Alternative empirical Bayes models for adjusting for batch effects in genomic studies
TL;DR: This work provides batch effect solutions for cases where the severity of the batch effects is not extreme, and forcases where one high-quality batch can serve as a reference, such as the training set in a biomarker study.

Patterning of wound-induced intercellular Ca(2+) flashes in a developing epithelium.

TL;DR: It is found that intercellular Ca(2+) transients show spatially non-uniform characteristics across the proximal-distal axis of the larval wing imaginal disc, which exhibit a gradient in cell size and anisotropy, and follows lines of mechanical tension at velocities that are largely independent of tissue heterogeneity and reflect the mechanical state of the underlying tissue.

Things I Have Learned (So Far).
TL;DR: The application of statistics to psychology and the other sociobiomedical sciences has been studied extensively as discussed by the authors, including the principles "less is more" (fewer variables, more highly targeted issues, sharp rounding off), "simple is better" (graphic representation, unit weighting for linear composites), and "some things you learn aren't so."
Journal ArticleDOI
To Explain or to Predict
TL;DR: The distinction between explanatory and predictive models is discussed in this paper, and the practical implications of the distinction to each step in the model- ing process are discussed as well as a discussion of the differences that arise in the process of modeling for an explanatory ver- sus a predictive goal.

Examining the Relationship Between Reviews and Sales: The Role of Reviewer Identity Disclosure in Electronic Markets
TL;DR: It is suggested that identity-relevant information about reviewers shapes community members' judgment of products and reviews and shows that shared geographical location increases the relationship between disclosure and product sales, thus highlighting the important role of geography in electronic commerce.

Examining the Relationship Between Reviews and Sales: The Role of Reviewer Identity Disclosure in Electronic Markets
TL;DR: In this paper, the authors used a unique data set based on both chronologically compiled ratings as well as reviewer characteristics for a given set of products and geographical location-based purchasing behavior from Amazon, and provided evidence that community norms are an antecedent to reviewer disclosure of identity-descriptive information.

Regression Methods in Biostatistics: Linear, Logistic, Survival, and Repeated Measures Models
TL;DR: McCoch as discussed by the authors provides a unified, in-depth, readable introduction to the multipredictor regression methods most widely used in biostatistics: linear models for continuous outcomes, logistic models for binary outcomes, the Cox model for right-censored survival times, repeated-measures models for longitudinal and hierarchical outcomes, and generalized linear model for counts and other outcomes.
