BINS

Type: Command

Description: Sort into Frequency Bins Command: Sorts the elements of the independent column (XCOL) of

the current statistics matrix (the reserved variable ΣDAT) into (nbins + 2) bins, where the left edge of bin 1 starts at value xmin and each bin has width xwidth.

BINS returns a matrix containing the frequency of occurrences in each bin, and a 2-element array containing the frequency of occurrences falling below or above the defined range of x-values. The array can be stored into the reserved variable ΣDAT and used to plot a bar histogram of the bin data (for example, by executing BARPLOT).

For each element x in ΣDAT, the nth bin count nfreq bin n is incremented, where:

n= IP x – xmin

freqbinn -------------------

xwidth

for xmin ≤ x ≤ xmax, where xmax = xmin + (nbins)(xwidth).

Example: If the independent column of ΣDAT contains the following data:

7 2 3 1 4 6 9 0 1 1 3 5 13 2 6 9 5 8 5

1 2 5 BINS returns [[ 5 ][ 3 ][ 5 ][ 2 ][ 2 ]] and [ 1 1 ] The data has been sorted into 5 bins of width 2, starting at x-value 1 and ending at x-value 11. The first element of the matrix shows that 5 x-values (2 1 1 1 2) fell in bin 1, where bin 1 ranges from x-value 1 through 2.99999999999. The vector shows that one x-value was less than xmin (0), and one was greater than xmax (13).
