LINFIT Formulator function
Finds a linear equation and returns a new column (vector).
Usage
LINFIT(VX, VY, STARTPOS, ENDPOS)
The name of any column (vector) listed under Columns
The name of any column (vector) listed under Columns
The row number (index) of the first set of
and
values
The row number (index) of the second set of
and
values
Details
Finds a linear equation of the form Y = a + bX from two sets of X and Y values selected from two
columns (vectors), VX and VY. This equation corresponds to a line drawn through two points on a
curve that is created by plotting the values in VY against the values in VX. The two points are
specified by the arguments STARTPOS and ENDPOS.
Using the linear equation, returns a new column (vector) containing Y values calculated from all X
values in column VX.
If a VX or VY value at either STARTPOS or ENDPOS is an invalid number (that is, the value is #REF),
the function will not return a valid result.
To return a linear regression fit for two columns (vectors), use the REGFIT function.
Example
RESISTORFIT = LINFIT (rESV, RESI, FIRSTPOS(rESV), LASTPOS(rESV))
