Quantlet: | cdfcl | |
Description: | Computes the values of the cumulative distribution function of classificated data at the point x |
Usage: | Fx = cdfcl(gr, fr, x) | |
Input: | ||
gr | m x n grid matrix, each column must be ordered ascendently | |
fr | (m-1) x n matrix of frequencies for each bin in each column | |
x | n x 1 vector of x values for each column or a scalar when x is the same for every column | |
Output: | ||
Fx | 1 x n row vector - values of the cummulative distribution function for each column |
library("stats") randomize(666) ; make four columns each with 15 random intervals gr = sort(normal(5,4)|5+normal(5,4)|10+normal(5,4),0) gr[,3] = 10 + gr[,3] fr = ceil(30*uniform(14)~20*uniform(14,2)~2*uniform(14)) x = #(-1,11,15,0.4) cdfcl(gr,fr,x)
