discrete curve


last updated: 2005-10-26

A discrete function has values only for the natural numbers (n). Giving to the interval [n - 1/2, n + 1/2] the value of f(n), we get a bar formed curve, a histogram.
When the discrete function gives a percentage, and the function values have been ordered from high to low, the curve is called a Pareto diagram.

We shall see that some discrete curves for large n can be approached by (often exponential) continuous functions.

The following discrete curves can be distinguished:
