STANDARD

***

VALUE

HISTOGRAM

FUNCTION

Processes input data as

either

a standard

histogram (frequency distribution) or

a

weighted

value

histogram.

The standard

histogram outputs the fraction

of

the Output

lnterval that the

value

in a specified

input location (defined as

the

bin select

value)

is

within a particular sub-range of the total

specified

range.

A

counter

in

the

bin associated

with each sub-range is incremented

whenever

the value falls within that

sub-range.

The value

which

is

output

to

Final Storage

for

each bin

is

computed by dividing

the

accumulated

total

in

each

bin by the

total

number of

scans.

This

form

of

output

is

also

referred

to

as

a

frequency

distribution.

The weighted

value histogram

uses data

from

2

input

locations. One

location contains

the

bin

select value; the other contains the weighted

value.

Each time

the

instruction is executed,

the weighted

value

is

added

to

a

bin.

The

sub-

range that

the

bin select

value

is in determines

the

bin

to which the weighted value

is

added.

When the

Output

Flag

is

set, the value

accumulated in each bin

is

divided

by

the

TOTAL

number of input scans

to

obtain

the

values that are output

to

Final Storage.

These

values are

the

contributions of

the

sub-ranges

to the overall weighted

value.

To

obtain

the

average

of

the weighted values that occurred

while

the

bin select value was within
