Statistics - MethodologyVariable selection is considered in the setting of supervised binaryclassification with functional data $\\{X(t),\\ t\\in[0,1]\\}$. By "variableselection" we mean any dimension-reduction method which leads to replace thewhole trajectory $\\{X(t),\\ t\\in[0,1]...
In statistics, most of the data you analyze are random variables, which are functions describing all values that occur during a series of random events or experiments. They can represent categorical, discrete, and continuous data. Examples include the following: Flipping coins or rolling dice and ...
In statistics, a variable can be something that has different values among subjects in a sample or population, like height or weight. An attribute, in the same field, can refer to a specific characteristic that can be used to categorize subjects, like gender or nationality. 11 A variable imp...
You can code a categorical variable to make it look like a quantitative one. For example, you could code eye color as 1:blue, 2:brown, 3: green or 4:hazel. Although this can be useful for data analysis,it doesn’t become a quantitative variable because you assigned it a number. Refer...
In the analysis of spatially resolved transcriptomics data, detecting spatially variable genes (SVGs) is crucial. Numerous computational methods exist, but varying SVG definitions and methodologies lead to incomparable results. We review 34 state-of-the-art methods, classifying SVGs into three categorie...

Here, we show that a bifactor model incorporating a task-general domain and splitting the cognitive systems domain better fits the examined corpus of tfMRI data than the current RDoC framework. We also identify the domain of arousal and regulatory systems as underrepresented. Our data-driven ...
