This means that the goodness of a process decreases with time, until it becomes zero when the time quantum of the task expires. The final goodness is calculated in function of the niceness of the process.

How to compute goodness of fit for a linear model in R

Webwhere: F = the cumulative distribution function for the probability distribution being tested.; Y u = the upper limit for class i,; Y l = the lower limit for class i, and; N = the sample size; The resulting value can be compared with a chi-square distribution to determine the goodness of fit.
