    Can someone tell me if the output of a process is classed as the numerical output of a random variable?Β  In my mind the process is the random variable and the numerical output (data) from the process creates the shape of the model.Β  Thanks

    Maybe we are just talking past one another but I’m not sure what you mean by β€œthe numerical output from the process creates the shape of the model.”

    A random variable is a function that takes a defined value for every point in sample space. – Statistical Theory and Methodology in Science and Engineering – Brownlee – pp. 21.Β  Given this I would say the process is the random variable and the output is just a quantification of what the random variable is doing. In other words – the random variable is going to determine the output distribution and all the numerical record is doing is cataloging that fact.
