CMB component separation by parameter estimation [PDF]
, 2005 We propose a solution to the CMB component separation problem based on standard parameter estimation techniques. We assume a parametric spectral model for each signal component, and fit the corresponding parameters pixel by pixel in a two-stage process ...

Detecting Violations of Unidimensionality by Order-Restricted Inference Methods
Frontiers in Applied Mathematics and Statistics, 2016 The assumption of unidimensionality and quantitative measurement represents one of the key concepts underlying most of the commonly applied of item response models.

Does the Mundell-Fleming model fit in China? [PDF]
Zbornik radova Ekonomskog fakulteta u Rijeci : časopis za ekonomsku teoriju i praksu, 2019 This paper examines the causal relationship between interest rate differential (IRD) and international short-term capital flow (SCF) to determine whether such a relationship in China supports the Mundell-Fleming model.

Model-based fit procedure for power-law-like spectra
, 2005 $1/f^\alpha$ noises are ubiquitous and affect many measurements. These noises are both a nuisance and a peculiarity of several physical systems; in dielectrics, glasses and networked liquids it is very common to study this noise to gather useful ...

A goodness of fit measure related to r² for model performance assessment [PDF]
, 2013 Checking the predictive worth of an environmental model inevitably includes a goodness of fit metric to quantify the degree of matching to recorded data, thereby giving a measure of model performance. Considerable analysis and discussion have taken place

Journal of the Royal Statistical Society Series B: Statistical Methodology, 1995 SUMMARY A robust method for fitting a model from a parametric family is fundamental to effective statistical analysis. A procedure is given for robustifying any model fitting process by using weights from the family from which the model is to be chosen.

Data Fit (Stress) vs. Model Fit (Recovery) in Multidimensional Scaling
Austrian Journal of Statistics, 2020 The paper studies the relation of data fit (Stress) and model fit (recovery of a true latent configuration superimposed with random error) depending on the number of points and the error level in the data when running ordinal and interval MDS.

A person-organization fit Model of Generation Z: Preliminary studies [PDF]
Journal of Entrepreneurship, Management and Innovation, 2020 The study looks at developing a person-organization fit model based on the unique characteristics of the new generational cohort, Generation Z, now entering the workforce. Theory suggests competitive advantage may come to a firm based on its unique human
