Display growth rate (immediate growth command)                 (STB-19: sts7.2)
----------------------------------------------

    ^growthi^ old_value new_value [^, noa^nnual ^la^g^(^#^) l^og ^p^ercent ^peri^od^(^#|str^)^]


Description
-----------

^growthi^ is an immediate version of the ^growth^ command.  It displays the growth
rate that transforms ^old_value^ to ^new_value^.  All the options, except ^lag()^,
are taken from ^growth^.  The ^ma()^ and ^suffix()^ options from ^growth^ are not
available since they do not make sense in an immediate command.

^old_value^ and ^new_value^ can be numbers or expressions.  If they are
expressions, you must surround them with double quotes (") if they contain
embedded spaces or commas.





Options
-------

^noannual^ specifies that the growth rate is not to be annualized.

^lag(^#^)^ specifies the number of periods between the old and the new values.
    The default lag is 1.

^log^ calculates the growth rate by taking the log difference of the new and
    old values.

^percent^ calculates the growth rate as a percent rather than a fraction.

^period(^#^)^ specifies the period of the data.  If this option is not specified,
    the value previously set with the ^period^ command is used.  If no value
    has been set, the value 1 (annual) is assumed.  ^period()^ may be specified
    as a number (interpreted as the number of observations per "year") or as
    a word such as "^weekly^", "^quarterly^", etc.  The period may be abbreviated
    as "^w^", "^q^", etc.; see ^help period^.






Examples
--------

 . ^growthi 15 17^

 . ^growthi revenue[17] 350, percent

 . ^growthi "27 + log(y[115])" z[_N], lag(4)
