The library DBMATH.LBR contains several higher math functions
and statistical analysis command programs for use with dBASE II.
Included are a natural log function (NATLOG), a base 10 log
function (LOG), and a square root function (SQRT). Any or all of
functions may be inserted into a dBASE command file using the
merge option of any word processor. Make sure that variables used
in the function do not interfere with those already in your
command file.

LINREG and STATS are statistical analysis command files providing
capability for least squares linear regression and descriptive
statistics respectively. LINREG produces slope, y intercept,
coefficient of determination (R^2), and standard error of
estimate. STATS produces average, minimum, maximum, range,
variance and standard deviation. To use either program,
enter a field name when prompted for variables and enter a
"CONDITION:" in the normal dBASE manner for specifying conditions,
ie. "X>0 .AND. #<>25" etc.
