Discrete Random Variables

The EJS Radioactive Decay Model simulates the decay of a radioactive sample using discrete random events. It displays the number of radioactive nuclei as a function of time. You can change the initial number of nuclei and the decay constant as well as changing the plot to a semi-log plot. The...

The EJS Radioactive Decay Events Model simulates the decay of a radioactive sample using discrete random events. It displays the number of events (radioactive decays) as a function of time in a given time interval. You can change the initial number of nuclei, the decay constant and the time...

This function generates a vector of triangular distributed continuous random variable. By specifying minimum value(a), maximum value(b), mode(c), and number of variables to be generated(n), the function gives a vector of random variables as output (X). The command syntax is X=trirnd(a,c,b,n).You...

Calculates entropy for data (probability of events) in an array. In information theory, entropy is a measure of the uncertainty associatedwith a random variable. In this context, the term usually refers to theShannon entropy, which quantifies the expected value of the information% contained in a...
