LINEST, Conditional ARRAY ???

[yum]

See data below. 100 is in cell A3 and 21 is in cell C13.
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o> </o>
I’m trying to return the slope for each “TYPE”. The LINEST function would appear appropriate coupled with conditional statements in the Known Ys and Known Xs all wrapped in array. The formula for the slope for TYPE 100 in cell F3 is
<o> </o>
“=LINEST(IF($A$3:$A$13=$E3,$B$3:$B$13),IF($A$3:$A$13=$E3,$C$3:$C$13))”
<o> </o>
followed by CTRL+SHIFT+ENTER. This formula does not return the slope and I’m not sure why. The same concept in the formula is entered for the Y-Intercept for Type 100 in cell G3 as
<o> </o>
“=INTERCEPT(IF($A$3:$A$13=$E3,$B$3:$B$13),IF($A$3:$A$13=$E3,$C$3:$C$13))”
<o> </o>
followed by CTRL+SHIFT+ENTER. This formula works just fine. Can anyone help me figure out the LINEST formulas in column F?<o></o>

I'm not able to to see the formulas. Can you simply copy/paste the data, the results, and formula?

 

[James02]

This is a copy of the original data set, plus I added a column (column D). Column A is the category/condition. Column B is the dependent variable ("known Y's" in LINEST). Column C & D are the independent variable ("known X's" in LINEST).

The function to calculate the intercept, & the two coefficients for the whole data set is: {=LINEST(B3:B13,C3:D13)}.

The function you provided a few years ago was this:

=LINEST(N(OFFSET($B$3:$B$13,SMALL(IF($A$3:$A$13=$J3,ROW($A$3:$A$13) - ROW($A$3)),ROW(INDIRECT("1:"&COUNTIF($A$3:$A$13,$J3)))),0,1)), N(OFFSET($C$3:$C$13,SMALL(IF($A$3:$A$13=$J3,ROW($A$3:$A$13)-ROW($A$3)),ROW(INDIRECT("1:"&COUNTIF($A$3:$A$13,$J3)))),0,1)))

I've tried adjusting the parameters to capture the second independent variable, but to no avail.

Try the following formula, which needs to be confirmed with CONTROL+SHIFT+ENTER...

=LINEST(N(OFFSET($B$3:$B$13,SMALL(IF($A$3:$A$13=$J3,ROW($A$3:$A$13) - ROW($A$3)),ROW(INDIRECT("1:"&COUNTIF($A$3:$A$13,$J3)))),0,1)), N(OFFSET($C$3:$D$13,SMALL(IF($A$3:$A$13=$J3,ROW($A$3:$A$13)-ROW($A$3)),ROW(INDIRECT("1:"&COUNTIF($A$3:$A$13,$J3)))),COLUMN($C$3:$D$13)-COLUMN($C$3),1,1)))

Hope this helps!

Hope this helps!

That works perfectly! Thank you. I never would of guessed the column function to solve it. You are a life saver. Thanks again.

 

[Domenic]

That's great. Glad I could help. And thanks for the feedback.

Cheers!
