MAXIMUM

NUMBER OF POSSIBLE

OUTPUTS

No limitation

exists on the number

of inputs that

can be

processed

by the CV/CR lnstruction,

but

the

processing

time and Intermediate

Storage

requirements

increase rapidly. The

instruction

requires

that the

input

values reside

sequentially

in

lnput

Storage.

Since

the number

of outputs

is

specified for

each type of statistical

calculation,

the instruction starts with

the first value,

working

sequentially

through

the input

values. For

this

reason,

the

order

of

the input values

determines

which

values

are

processed.

DEFINITION

Mean

of Kth value

Variance

of

Kth

value

Standard deviation of Kth

value

Covariance

of Kth and lth

value

Table 10-8

shows

the maximum number

of

outputs which can be

generated

and

the output

order for

K input

values located

sequentially

in

Input

Storage.

The output

order shown in Table

10-2 flows

from

left

to

right

and top to

bottom.

INSTRUCTION PROCESSING

The

CV/CR

Instruction contains

3 separate

processing phases:

1. Input Processing

2. Averaging

Period Processing

3. Output Processing
