Gini estimation under infinite variance [PDF]

open access: yes, 2017
We study the problems related to the estimation of the Gini index in presence of a fat-tailed data generating process, i.e. one in the stable distribution class with finite mean but infinite variance (i.e. with tail index $\alpha\in(1,2)$). We show that,

Amplitude variation in calibrated audiometer systems in Clinical Simulations

open access: yesNoise and Health, 2014
Manual pure tone audiometry is considered to be the gold standard for the assessment of hearing thresholds and has been in consistent use for a long period of time.

On Linearly Constrained Minimum Variance Beamforming [PDF]

open access: yes, 2015
Beamforming is a widely used technique for source localization in signal processing and neuroimaging. A number of vector-beamformers have been introduced to localize neuronal activity by using magnetoencephalography (MEG) data in the literature ...

Contrast Adaptation in Face Perception Revealed Through EEG and Behavior

open access: yesFrontiers in Systems Neuroscience, 2021
Exposure to a face can produce biases in the perception of subsequent faces. Typically, these face aftereffects are studied by adapting to an individual face or category (e.g., faces of a given gender) and can result in renormalization of perceptions ...

Watermark Embedding Scheme with Variance of Chromatic Components

open access: yesEngineering Proceedings, 2023
This paper contains the idea of inserting a watermark with the variance of color components of the image. The color image is converted into CIE color space.

Quality of life and associated factors in Swiss trans people: a cross-sectional study

open access: yesFrontiers in Psychiatry
BackgroundExperiences of stressful life events during transition may have a negative impact on quality of life (QoL) in trans persons. Little attention has been paid to this population in Switzerland, resulting in sparse data on their QoL and associated ...

Experimental Design Modulates Variance in BOLD Activation: The Variance Design General Linear Model

open access: yes, 2018
Typical fMRI studies have focused on either the mean trend in the blood-oxygen-level-dependent (BOLD) time course or functional connectivity (FC). However, other statistics of the neuroimaging data may contain important information.

Variance estimation for a low-income proportion [PDF]

open access: yes, 2003
Proportions below a given fraction of a quantile of an income distribution are often estimated from survey data in poverty comparisons. We consider the estimation of the variance of such a proportion, estimated from Family Expenditure Survey data.

Genetic parameters of agro-morpho-physiological traits in rice (Oryza sativa L.) [PDF]

open access: yesElectronic Journal of Plant Breeding, 2012
To estimate genetic variability, heritability and genetic advance a study was conducted on 10 diverse parents (3 CMS lines and 7advance breeding lines) and 21 hybrids of rice.

Noise Variance Estimation In Signal Processing [PDF]

open access: yes, 2007
We present a new method of estimating noise variance. The method is applicable for 1D and 2D signal processing. The essence of this method is estimation of the scatter of normally distributed data with high level of outliers. The method is applicable
