Total Variation: The TV distance between two distributions is: Z. TV(P; Q) = sup jP (A) Q(A)j = sup j (p(x) q(x))dxj; where A is just any measurable subset of the sample space, i.e. the TV distance is measuring the maximal di erence between the probability of an event under P versus under Q.
In statistics, probability theory, and information theory, a statistical distance quantifies the distance between two statistical objects, which can be two random variables, or two probability distributions or samples, or the distance can be between an individual sample point and a population or a wider sample of points.
The concept of statistical distance is useful when we want to identify objects that are in some sense close to each other. Such measures of distance are useful in classic statistical techniques such as clus-tering and classification, where we attempt to categorize data into distinct classes.
INTRODUCTION TO STATISTICAL ANALYSIS. LEARNING OBJECTIVES: After studying this chapter, a student should understand: notation used in statistics; how to represent variables in a mathematical form for statistical purposes; how to construct frequency distributions, histograms, and bar graphs;
9 lip 2020 · In quantitative research, after collecting data, the first step of statistical analysis is to describe characteristics of the responses, such as the average of one variable (e.g., age), or the relation between two variables (e.g., age and creativity).
