Discrete and Continuous Domains A discrete domain is a set of input values that consists of only certain numbers in an interval. 14 T�6m�V�@%iӦm� While a discrete PDF (such as that shown above for dice) will give you the odds of obtaining a particular outcome, probabilities with continuous PDFs are matters of range, not discrete points. Discrete data contains distinct or separate values. Data can be Descriptive (like "high" or "fast") or Numerical (numbers). discrete variable. ; Continuous data can take any value, including decimals. Similarly if x is a continuous random variable and f (x) is the PDF of x then, CDF for Continuous random variable. discrete data set and a continuous (scalar or vector) data set, using a similar approach to that of Ref. 3.
