A new approach to simple correspondence analysis with emphasis on the violation of the independence assumption of the levels of categorical variables

open access: yesActa Scientiarum: Technology, 2018
The main hypothesis of correspondence analysis is given by the independence between the levels of categorical variables. Due to violation of this hypothesis, this study aims to improve the technique of correspondence analysis, providing a new approach ...

Residual analysis for the identification of potential mid-infrared-derived biomarkers of heat stress in dairy cattle

open access: yesJournal of Dairy Science
: Numerous prediction equations have been developed based on mid-infrared (MIR) spectra, and some could be potentially used as biomarkers of heat stress.

Ensembles of physics-enhanced neural networks for the prediction of critical heat flux in nuclear reactors and the quantification of its uncertainty

open access: yesFrontiers in Nuclear Engineering
The Critical Heat Flux (CHF) is a physical phenomenon that may cause the deterioration of the heat transfer in the core of nuclear reactors, potentially leading to core damage.

Application of Fourier transform in processing inter-satellite measurements [PDF]

open access: yesКосмические аппараты и технологии
The article presents a method for noise filtering in inter-satellite measurements based on Fourier transform and adaptive colored noise processing. The relevance of the study stems from the need to enhance the accuracy of satellite navigation systems ...

Sine-Fitting Residual Root Mean Square, Mean, and Variance in the Presence of Phase Noise or Jitter

open access: yesSci
Fitting a sinusoidal model to a set of data points is a common practice in engineering, where one wants to estimate some quantities of interest by carrying out a sequence of measurements on a physical phenomenon.

Randomized Predictive P-values: A Versatile Model Diagnostic Tool with Unified Reference Distribution

open access: yes, 2019
Examining residuals such as Pearson and deviance residuals, is a standard tool for assessing normal regression. However, for discrete response, these residuals cluster on lines corresponding to distinct response values.

Residual log-periodogram inference for long-run relationships [PDF]

open access: yes, 2006
We assume that some consistent estimator of an equilibrium relation between non-stationary series integrated of order d(0.5,1.5) is used to compute residuals (or differences thereof).

Calibration of the EDGES High-Band Receiver to Observe the Global 21-cm Signature from the Epoch of Reionization [PDF]

open access: yes, 2016
The EDGES High-Band experiment aims to detect the sky-average brightness temperature of the $21$-cm signal from the Epoch of Reionization (EoR) in the redshift range $14.8 \gtrsim z \gtrsim 6.5$.

On robust analysis of paycheck: case study

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
Many statistical tests are constructed to check the validity of normal distribution. Here we propose a case study on analysis of paycheck where we employ the RT class of tests for normality firstly introduced in Střelec, Stehlík (2008).
