Non-Parametric Model

Non-parametric Models are statistical models that do not often conform to a normal distribution, as they rely upon continuous data, rather than discrete values. Non-parametric statistics often deal with ordinal numbers, or data that does not have a value as fixed as a discrete number. The term non-parametric does not mean that the value lack inherent parameters, but rather that the parameters are flexible and can vary. One may turn to non-parametric statistics when dealing with ranked data, in which some of the value of the variables is the order in which they are organized.
