Excel Statistical Comparison of Two Data Sets Introduction We will use two monthly sales datasets of Steel-cut oats and Rolled oats. We will determine how sales of these two types of oats change over time. We w
Eighty-eight students in grades 3 to 9 were presented with data sets in graphical form for comparison. Student responses were analysed according to a developmental cycle which was repeated in two contexts: one where the numbers of values in the data sets were the same and the other where ...
This package facilitates this recent movements by providing the necessary methodological tools. The Network Comparison Test (NCT) uses resampling-based permutation testing to compare network structures from two independent, cross-sectional data sets on invariance of 1) network structure, 2) edge (connect...
The basic principle of Statistical Learning Theory (SLT) essentially coincides with the aims of machine learning in general in that an algorithm is defined which learns a relationship between two sets of data. The first is defined on a d-dimensional input space and denoted x̲, the second is...
When data are not normal and have differing variances, we propose data sets are better analysed by a bootstrap method that tests the null hypothesis that means (or medians) are the same between two conditions, instead of the commonly used Mann-Whitney-Wilcoxon test. We illustrate this with ...
rather naive and unverified. While the procedures for comparison of a pair of classifiers on a single problem have been proposed almost a decade ago, comparative studies with more classifiers and/or more data sets still employ partial and unsatisfactory solutions. ...
The presented study focuses on the statistical comparison and ascertainment of relations between three datasets collected from selected Norway spruce forest stands in the Ore Mountains, Czechia. The data sets comprise i) photosynthetic pigments (chlorophylls, carotenoids) and water content of 495 samples...
Comparison of two-state model parameters between the perturbation planes. (A) Estimated fast and slow retention (\(a_{f,jp} ,\;a_{s,jp}\)), learning rates (\(b_{f,jp} ,\;b_{s,jp}\)), and measurement and planning variabilities (\(\sigma_{x,jp}\), \(\sigma_{u,jp}\)) ...
For the following more detailed statistical comparisons, we defined two sets of taxonomicgroups, considering both biological and coverage aspects. Taxonomy Set 1 (Table1) was defined to provide an overview of the total content of the two databases used for the general comparison of bacterial and ...
If a cultural feature is transmitted over generations and exposed to stochastic selection when spreading in a population, its evolution may be governed by statistical laws and be partly predictable, as in the case of genetic evolution. Music exhibits ste
