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
