Example 2. Suppose that there are two red balls and three white balls in a bag, catch one ball from the bag twice without put back, and define X and Y as follows: ball white is put second the 0 ball red is put second the 1 ball white is put first the 0 ball red is put fi...

Example. Consider an experiment that consists of tossing a die and a coin at the same time. We can consider a number of random variables defined on this sample space. We will assign an indicator random variable to the result of tossing the coin. If it comes up heads we will assign a ...
There are three options for the Initialization Method parameter: Optimized seed locations, User defined seed locations, and Random seed locations. Seeds are the features used to grow individual clusters. If, for example, you enter 3 for the Number of Clusters parameter, the analysis will begi...

Random samples consistently yielded around 9–11 optimal clusters, with one example (10 clusters) shown in this panel. A Jaccard similarity of 0.25 corresponds to two subsets having 4 out of 10 nodes in common. b Frequency of individual node participation across 100,000 synergistic subsets, ...

For example, a test with five elements with three variations each will generate 1,024 combinations (4x4x4x4x4). To compare the different optimization methods let’s illustrate the number of visitors required for a full factorial testing of two variable elements. Each variable is represented by ...
Example – Crime Rates by State 2-3 components explain 76%-87% of the variance First principal component has uniform variable weights, so is a general crime level indicator Second principal component appears to contrast violent versus property crimes ...
