What does the narcissistic personality inventory really measure?

The Narcissistic Personality Inventory (NPI) is a widely used measure of narcissism. However, debates persist about its exact factor structure with researchers proposing solutions ranging from two to seven factors. The present research aimed to clarify the factor structure of the NPI and further illuminate its nomological network. Four studies provided support for a three-factor model consistin...

What accuracy statistics really measure

This paper aims to provide the software estimation research community with a better understanding of the meaning of, and relationship between, two statistics that are often used to assess the accuracy of predictive models: the mean magnitude relative error, MMRE, and the number of predictions within 25% of the actuals, pred(25). We demonstrate that MMRE and pred(25) are, respectively, measures ...

What Does PLIER Really Do?

MOTIVATION Our goal was to understand why the PLIER algorithm performs so well given its derivation is based on a biologically implausible assumption. RESULTS In spite of a non-intuitive assumption regarding the PM and MM errors made as part of the derivation for PLIER, the resulting probe level error function does capture the key characteristics of the ideal error function, assuming MM probe...

What does % V actually measure ?

The system of classifying languages by their rhythmic patterning traditionally and historically characterizes the patterns in terms of three groups. One group includes the so-called “stress-timed” languages like English, German, and Dutch, which are perceived as having equal intervals between stresses, and are described as sounding rhythmically like Morse code (James 1940). A second rhythmic cl...
