In the end we are most of the time dealing with discrete variables – although from a theoretical point of view they are continuous – and that has a real impact for instance for classification.Recall Strobl's paper indicating that Random Forests is biased towards variables with multiple cutting points (higher accuracy but potentially similar nature). Strobl C., Boulesteix A.-L., Zeileis A., & Hothorn T. Bias in random forest variable importance measures: illustrations, sources and a solution. doi: 10.1186/1471-2105-8-25 Discrete data take particular values, while continuous data are not restricted to separate values.From my personal experience probabilistic neural networks may present also a bias when variables present different accuracy unless they are of the same type (i.e., continuous). Discrete data are distinct and there is no grey area in between, while continuous data occupy any value over a continuous data value.

All actual sample spaces are discrete, and all observable random variables have discrete distributions. Of course, any measurement of these variables will be finitely accurate and in some sense discrete.

The continuous distribution is a mathematical construction, suitable for mathematical treatment, but not practically observable. It is useful to distinguish between ordered (i.e., ordinal), unordered (i.e., nominal), and binary discrete variables.

discrete are relevant depending on the ‘environment’.

Oh, what a tangled web is weaved as growing numbers of married women and men sneak into Internet chat rooms for romantic or sexual thrills, a University of Florida study finds."Never before has the dating world been so handy for married men and women looking for a fling," said Beatriz Avila Mileham, who conducted the research for her doctoral dissertation in counselor education at UF.

(It) can't get any easier than that." Counseling organizations report chat rooms are the fastest-rising cause of relationship breakdowns, and the problem only stands to get worse as today's population of Internet users continues to grow, Mileham said."The Internet will soon become the most common form of infidelity, if it isn't already," she said.

Unlike some fatal attractions, a simple click of a mouse button ends contact – should the person want to break it off – without any explanations or apologies, she said.

"And now we come to the great question as to the reason why. I was inclined from the first to the latter supposition.

Robbery has not been the object of the murder, for nothing was taken. Political assassins are only too glad to do their work and to fly.

Discrete data can be numeric -- like numbers of apples -- but it can also be categorical -- like red or blue, or male or female, or good or bad.
