Classification of the coefficient of variation for experiments with eucalyptus seedlings in greenhouse

open access: yesRevista Ciência Agronômica, 2021
In experimental statistics, the variability, which allows for conclusions related to experimental accuracy, is usually demonstrated by means of experimental coefficient of variation (CV).

Landmark-free, parametric hypothesis tests regarding two-dimensional contour shapes using coherent point drift registration and statistical parametric mapping [PDF]

open access: yesPeerJ Computer Science, 2021
This paper proposes a computational framework for automated, landmark-free hypothesis testing of 2D contour shapes (i.e., shape outlines), and implements one realization of that framework.

Nonparametric statistical tests for the continuous data: the basic concept and the practical use [PDF]

open access: yesKorean Journal of Anesthesiology, 2016
Conventional statistical tests are usually called parametric tests. Parametric tests are used more frequently than nonparametric tests in many medical articles, because most of the medical researchers are familiar with and the statistical software ...

Multiple Outlier Detection Tests for Parametric Models

open access: yesMathematics, 2020
We propose a simple multiple outlier identification method for parametric location-scale and shape-scale models when the number of possible outliers is not specified.

The shifting boxplot. A boxplot based on essential summary statistics around the mean.

open access: yesInternational Journal of Psychological Research, 2010
Boxplots are a useful and widely used graphical technique to explore data in order to better understand the information we are working with. Boxplots display the first, second and third quartile as well as the interquartile range and outliers of a data ...

Unexpected failures of recommended tests in basic statistical analyses of ecological data [PDF]

open access: yesWeb Ecology, 2008
Ecologists, when analyzing the output of simple experiments, often have to compare statistical samples that simultaneously are of uneven size, unequal variance and distribute non-normally.

A Comparison of Nonparametric Statistics and Bootstrap Methods for Testing Two Independent Populations with Unequal Variance

open access: yesInternational Journal of Analysis and Applications, 2023
The common parametric statistics used for testing two independent populations have often required the assumptions of normality and equal variances. Nonparametric tests have been used when assumptions of parametric tests cannot be achieved.
