SYNOPSIS
SUBROUTINE FREQ(X,N)
REAL(kind=wp),intent(in) :: X(:) INTEGER,intent(in) :: N
DESCRIPTION
freq(3f) computes the sample frequency and sample cumulative frequency for the data in the input vector x.
INPUT ARGUMENTS
X The vector of (unsorted or sorted) observations. N The integer number of observations in the vector X. The maximum allowable value of N for this subroutine is 15000.
OUTPUT
Several (for large data sets) pages of automatic plots (with approximately 55 values per page) consisting of an ordered listing of each distinct value in the data set along with the frequency of occurrence of that value and the cumulative frequency.
EXAMPLES
Sample program:
program demo_freq use M_datapac, only : freq implicit none ! call freq(x,y) end program demo_freqResults:
