The independent variableis the variable that is controlled and manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable. The dependent variable is the variable that is measured by the ex...

This decision to concentrate on the first measured parameters at admission is deliberate, aiming to strike a balance between model intricacy and practical applicability. When employing various ML methods, a crucial point for discussion arises: how to reconcile the differences in the sets of features ...
athe same variable (dominance) was framed as either a strategic (how) variable or as an outcome(what) variable. 同一可变物(优势)被构筑了作为战略(怎么)可变物或作为结果(什么)可变物。[translate]
Precision, F-measure, Specificity, Accuracy, Sensitivity, ROC area, and PRC were measured to compare feature selection methods' effect on prediction algorithms. The results demonstrate that feature selection resulted in significant improvements in model performance in some methods (e.g., j48), ...
Dependent Variable: Test Mark (measured from 0 to 100)Independent Variables: Revision time (measured in hours) Intelligence (measured using IQ score)The dependent variable is simply that, a variable that is dependent on an independent variable(s). For example, in our case the test mark that ...
When a qubit given by the quantum state vector [αβ] is measured, the outcome 0 is obtained with probability |α|2 and the outcome 1 with probability |β|2. On outcome 0, the qubit's new state is [10]; on outcome 1 its state is [01]. Note that these probabilities sum up to ...
Specifically, the blood donation anxiety (BDA) construct was adapted from Chen, Zhou, Zhang and Xiao [38] and Robinson, Masser, White, Hyde and Terry [38,59], and measured on a three-item scale. The scale includes the following statements: “In the future if I donate blood, I would ...
In this guide, we’ll cover the fundamentals of regression analysis, what it is and how it works, its benefits and practical applications.
site and by reviewing relevant literature (Table2, seeSM 8: Social support instrument). Psychobiological vulnerability can moderate the links between social determinants and mental illness but was assumed to vary randomly in the population in relation to the exposure variable and was not measured. ...
