The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics

International Journal of Cosmetic Science, Volume 48, Issue 3, Page 600-634, June 2026.
This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...

Spatial depth for data in metric spaces

Scandinavian Journal of Statistics, Volume 53, Issue 2, Page 684-711, June 2026.
Abstract We propose a novel measure of statistical depth, the metric spatial depth, for data residing in an arbitrary metric space. The measure assigns high (low) values for points located near (far away from) the bulk of the data distribution, allowing quantifying their centrality/outlyingness.

Meow the Eleventh - CDA, QDA, and CAT

, 2014
CDA via CAT sounds ominous, but actually no secret is buried here. CDA stands for Critical Discourse Analysis, QDA is short for Qualitative Data Analysis, and CAT is, apart from being the word for feline friends, an abbreviation of a software available on the net, namely Coding Analysis Toolkit.

Spectrally-Corrected and Regularized QDA Classifier for Spiked Covariance Model

CoRR
Quadratic discriminant analysis (QDA) is a widely used method for classification problems, particularly preferable over Linear Discriminant Analysis (LDA) for heterogeneous data. However, QDA loses its effectiveness in high-dimensional settings, where the data dimension and sample size tend to infinity.

Liver cirrhosis prediction: The employment of the machine learning-based approaches

Intelligent Systems with Applications
Early detection of liver cirrhosis remains problematic due to its asymptomatic onset and the inherent class imbalance in clinical data. This study conducts a comprehensive evaluation of machine learning models for predicting cirrhosis stages, with a ...

System prompts in QDA software: an investigation

Sozialwissenschaftliche Methodenberatung
While writing this blog post, I felt like an investigative journalist. My aim was to find out which system prompts are used in qualitative data analysis (QDA) software. An increasing number of QDA software packages include so-called AI assistants or have been specifically designed for qualitative research using large language models (LLMs), such as ...

A Quality-Gating and Delay-Alignment State-Space Framework for Radar-Based IBI/HRV Detection

IEEE Access
Inter-beat interval and heart rate variability are essential indicators of cardiovascular and autonomic function, yet their reliable estimation from radar signals remains challenging owing to time-varying observability, multipath interference, coherence ...

Generalizing

Grounded Theory Review: An International Journal, 2006
In this chapter I wish to explore this struggle for the purpose of explaining that the various contra arguments to using descriptive generalizations DO NOT apply to the ease of using conceptual generalizations yielded in SGT and especially FGT.

A new method for identifying bivariate differential expression in high dimensional microarray data using quadratic discriminant analysis

BMC Bioinformatics, 2011
Background One of the drawbacks we face up when analyzing gene to phenotype associations in genomic data is the ugly performance of the designed classifier due to the small sample-high dimensional data structures (n ≪ p) at hand.

Growing Open: The transition from QDA to Grounded Theory

Grounded Theory Review: An International Journal, 2006
Doing a PhD can principally be carried out in three ways; firstly by applying existing theories on new data, secondly by theoretically comparing existing theories and thirdly by generating a new theory.
