INTERVAL COUNT

Name:
    INTERVAL COUNT (LET)
Type:
    Let Subcommand
Purpose:
    Compute the number of elements in a variable that lie within a user-specified interval.
Syntax:
    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>
Examples:
    LET LOWLIMIT = 0
    LET LOWLIMIT = 10
    LET N = INTERVAL COUNT Y1
Note:
    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.
Note:
    Dataplot statistics can be used in a number of commands. For details, enter

Program:
     
    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
