INTERARRIVAL TIME

Name:
    INTERARRIVAL TIME (LET)
Type:
    Let Subcommand
Purpose:
    Compute the interarrival times for a set of failure times.
Description:
    The interarrival times, T, for a set of N failure times X are computed by sorting the data, setting T(1) = X(1), and the setting T(I) = X(I) - X(I-1) for I = 2 through N.
Syntax:
    LET <resp> = INTERARRIVAL TIME <x1>             <SUBSET/EXCEPT/FOR qualification>
    where <x1> is the variable for which the interarrival times are to be computed;
                <resp> is a variable where the interarrival times are saved;
    and where the <SUBSET/EXCEPT/FOR qualification> is optional.
Examples:
    LET IA = INTERARRIVAL TIME X
Default:
    None
Synonyms:
    None
