| kzs.params {kzs} | R Documentation |
For an n-dimensional input data set, this function will calculate the values by
which the parameters delta and d are bounded by.
kzs.params(x, dimension)
x |
a matrix or data frame containing the input data that is to be used in kzs, kzs.2d,
or kzs.md.
|
dimension |
an integer specifying the dimensionality of x.

The compilation of functions within the kzs package requires the specification of two
parameters: the first is delta, the physical range of smoothing along each variable
in x; the second is d, a scale reading of each corresponding input variable
in x. Each parameter is subject to two restrictions; delta and d must both
be positive real numbers, each d must be less than or equal to the difference of sorted,
consecutive x values and each delta must be much less than the difference of the
maximum and minimum values for each corresponding input variable in x. Hence, for each
input variable in x, there must be a corresponding delta and d. This function
was developed to be used prior to any of the functions within kzs in order to increase the
efficiency of use.
