An Unbiased Method of Measuring the Ratio of Two Data Sets
The Astrophysical Journal Supplement Series, 2023 In certain cases of astronomical data analysis, the meaningful physical quantity to extract is the ratio R between two data sets. Examples include the lensing ratio, the interloper rate in spectroscopic redshift samples, and the decay rate of ...

BATHYMETRY FROM WORLDVIEW-3 SATELLITE DATA USING RADIOMETRIC BAND RATIO
Acta Polytechnica, 2018 The use of optical satellite sensors allows to obtain bathymetry data on large area ina short time and in a cheap way. In addition, in particular places where it is difficult to carry out the survey by classic methods, the bathymetry from satellite data ...

Homogeneity Test for Multiple Semicontinuous Data with the Density Ratio Model
Mathematics, 2023 The density ratio model has been widely used in many research fields. To test the homogeneity of the model, the empirical likelihood ratio test (ELRT) has been shown to be valid. In this paper, we conduct a parametric test procedure.

Estimating adjusted prevalence ratio in clustered cross-sectional epidemiological data
BMC Medical Research Methodology, 2008 Background Many epidemiologic studies report the odds ratio as a measure of association for cross-sectional studies with common outcomes. In such cases, the prevalence ratios may not be inferred from the estimated odds ratios.

Learning sparse log-ratios for high-throughput sequencing data [PDF]
Bioinformatics, 2021 Abstract Motivation The automatic discovery of sparse biomarkers that are associated with an outcome of interest is a central goal of bioinformatics. In the context of high-throughput sequencing (HTS) data, and compositional data (CoDa) more generally, an important class of biomarkers are the ...

New empirical fits to the proton electromagnetic form factors [PDF]
, 2001 Recent measurements of the ratio of the elastic electromagnetic form factors of the proton, G_Ep/G_Mp, using the polarization transfer technique at Jefferson Lab show that this ratio decreases dramatically with increasing Q^2, in contradiction to ...

Data Clustering on Breast Cancer Data Using Firefly Algorithm with Golden Ratio Method
Advances in Electrical and Computer Engineering, 2015 Heuristic methods are problem solving methods. In general, they obtain near-optimal solutions, and they do not take the care of provability of this case.

Nonmetric Scaling of Loudness-Ratio Data [PDF]
The Journal of the Acoustical Society of America, 1971 Loudness scales for 1-kHz tones, as determined by conventional scaling procedures, have yielded conventional loudness functions which grow as approximately the 0.50 power of the sound pressure. That is, a 10-dB increase in intensity corresponds roughly to a doubling of loudness.

GUIDELINES FOR VALIDATING BOWEN RATIO DATA [PDF]
Transactions of the ASAE, 2003 For a variety of reasons, the measurement of latent heat flux using the Bowen ratio method can sometimes result in erroneous data. This study provides guidelines for detecting erroneous Bowen ratio data and illustrates the application of these guidelines by comparing Bowen ratio and lysimeter data collected over grass and alfalfa in southern Idaho ...
