This function generates an empirical PDF using dy.dx on NNS.CDF.

Usage

NNS.PDF(variable, degree = 1, target = NULL, bins = NULL, plot = TRUE)

Arguments

variable

a numeric vector.

degree

integer; (degree = 0) is frequency, (degree = 1) (default) is area.

target

a numeric range of values [a,b] where a < b. NULL (default) uses the variable min and max observations respectively.

bins

integer; NULL Selects number of bins. Bin width defaults to density(x)$bw.

plot

logical; plots PDF.

Value

Returns a data.table containing the intervals used and resulting PDF of the variable.
