PERCENT ACCEPTABLE

PERCENT ACCEPTABLE (LET)

Let Subcommand

Compute the percentage of acceptable values for a variable.

The percent defective is the number of values of a variable (expressed as a percentage) that fall outside some user specified tolerance limits. Similiarly, the percent acceptable is the number of values (expressed as a percentage) that fall within some user specified tolerance limits.

LET <par> = PERCENT ACCEPTABLE <x>
                        <SUBSET/EXCEPT/FOR qualification>
where <x> is the variable for which the percent acceptable is computed;
            <par> is a parameter where the computed percentage acceptable is saved;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET A = PERCENT ACCEPTABLE Y1
LET A = PERCENT ACCEPTABLE Y1 SUBSET TAG > 2

The upper and lower specification limits must be specified by the user as follows:
LET LSL = <value>
LET USL = <value>
