INTERVAL COUNT

INTERVAL COUNT (LET)

Let Subcommand

Compute the number of elements in a variable that lie within a user-specified interval.

LET <par> = INTERVAL COUNT <y>
                        <SUBSET/EXCEPT/FOR qualification>
where <y> is the response variable;
            <par> is a parameter where the interval count is saved;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

The interval is specified with the commands

LET LOWLIMIT = <value>
LET UPPLIMIT = <value>

LET LOWLIMIT = 0
LET LOWLIMIT = 10
LET N = INTERVAL COUNT Y1

If LOWLIMIT is not defined, then the smallest number (PROBE CPUMIN) is used. Likewise, if UPPLIMIT is not defined, then the largest number (PROBE CPUMAX) is used.

Dataplot statistics can be used in a number of commands. For details, enter

LET Y1 = NORMAL RANDOM NUMBERS FOR I = 1 1 10000
LET Y2 = CAUCHY RANDOM NUMBERS FOR I = 1 1 10000
LET LOWLIMIT = 3
LET C1 = INTERVAL COUNT Y1
LET C2 = INTERVAL COUNT Y2
PRINT "NUMBER OF NORMAL RANDOM NUMBERS > 3 (OUT OF 10,000) = ^C1"
PRINT "NUMBER OF CAUCHY RANDOM NUMBERS > 3 (OUT OF 10,000) = ^C2"
    

The following output is returned

NUMBER OF NORMAL RANDOM NUMBERS > 3 (OUT OF 10,000) = 9
NUMBER OF CAUCHY RANDOM NUMBERS > 3 (OUT OF 10,000) = 996
