A method to identify a relationship between at least pairs of variables in a dataset generates a novel measure of dependence, referred to as a Maximal Information Coefficient (MIC), that captures a wide range of interesting associations (not limited to specific function types such as linear, ...
Diagnostic techniques are developed that aid in the systematic location of data points that are unusual or inordinately influential, and measure the presence and intensity of collinear relations among the regression data and help to identify variables involved in each and pinpoint estimated coefficients ...
Statisticians consider standardized regression coefficients to be a standardized effect size because they indicate the strength of the relationship between variables without using the original data units. Instead, this measure indicates the effect size in terms of standard deviations. Effect sizes help you...
The second sample of 143 students provided data to test the proposed model through a confirmatory factor analysis. A three-factor model was suggested in the first set of analyses, and evidence supporting the proposed model is provided in the confirmatory analysis. The three latent variables are ...
Scores were derived from data on life history traits and ecological requirements of individual species, with respect to their sensitivity to changes in landscape and the composition and qualities of ecosystems. Twelve variables were considered, related to the distribution, demography, ecological ...
giving sequence in spell (0 for not in spell, or integers 1 up); and indicating whether observations occur at the end of spells (0 or 1). By default, these variables will be called_spell,_seq, and_end. If the data are panel data, all operations are automatically performed separately ...
The uncontrolled manifold concept: identifying control variables for a functional task The degrees of freedom problem is often posed by asking which of the many possible degrees of freedom does the nervous system control? By implication, othe... JP Scholz,G Sch?Ner - 《Experimental Brain Research...
Accessibility factors Four accessibility variables such as distance to main roads, distance to railways, distance to city center and distance to rivers were extracted from National Administration of Surveying, Mapping and Geoinformation of China (http://218.244.250.78/NgccDigitalHall/). The data in 20...

Based on the internal dependence of variables, the variables with intricate and complex relationships are classified into a few comprehensive factors (Kaiser, 1958; Davis, 1986). In the study of flow units, reservoir evaluation parameters are numerous and the relationships among parameters are complex...
