Result
Returns the least common multiple of valueA and valueB,
which can be real numbers or lists.
Returns the number of characters in string.
Draws a line from (X1,Y1) to (X2,Y2).
Erases a line from (X1,Y1) to (X2,Y2).
Fits a linear regression model to Xlistname and Ylistname
with frequency freqlist, and stores the regression equation
to regequ.
Fits a linear regression model to Xlistname and Ylistname
with frequency freqlist, and stores the regression equation
to regequ.
Performs a linear regression and computes the t
confidence interval for the slope coefficient b.
Performs a linear regression and a t-test. alternative=
<; alternative=0 is ƒ ; alternative=1 is >.
Returns a list containing the differences between
consecutive elements in list.
Fills matrixname column by column with the elements from
each specified listname.
Returns the natural logarithm of a real or complex number,
expression, or list.

Ylistname with frequency freqlist, and stores the regression
equation to regequ.
Returns logarithm of a real or complex number,
expression, or list.
Returns the logarithm of a specifed value determined from
a specified base: logBASE(value, base).
