Neeraj Sir,

In his previous post, I asked him there must be some logic for multiplication, if we have to count number of times, which will not help getting shorter formula.

Ian,

Please explain logic behind it
You have inconsistent formulas in column B so before copying the suggested formula down the rows, remember to change the formula where formula changes by following the method used in the suggested formula.
e.g. the formula changes in B13 so change your formula here instead of copying the formula from B12 down the cells.

In B13
=G13^6*J13^3*M13^5*S13^3

Same way adjust all your formulas in column B.
@Shums
Maybe you are right though I don't see any pattern. :)

The logic behind it is to weight the multiplier to suit the model.
In the attached sheet there are two models ...... rows 5:12 and 13:24
taking  cells B5:B12 as an example col 'P' is most significant followed
by column 'D'
Neeraj,
My keyboard doesn't have the power symbol. Normally it's the left key on the top row.
Can you tell me the shortcut method to insert it ?
Thanks
Ian
It is Shift+6.
Or you can use Alt+94.
And your min 99.99 still be with this formula?
Hi Shums,
Yes the 99 min worked perfectly but since found that the idea was not so good after all :)
Please check your formula for B24. Doesn't seems to calculate as per your model 1200
B24 where model is 1200 in Column A:
=D24*D24*D24*G24*G24*N24*N24*N24*N24*N24*S24

Open in new window

B23 where model is 1200 in Column A:
=G23*G23*G23*G23*G23*G23*J23*J23*J23*M23*M23*M23*M23*M23*S23*S23*S23*S23

Is there any other logic?
Yes that works Neeraj. The power above 6 looked a little different
cheers
Ian
Anyway, you can use below formula for changing patterns.
=IF(A21=800,D21^4*G21^2*J21^3*P21^6,G21^6*J21^3*M21^5*S21^4)

You're welcome Ian! Glad it worked.
yes I messed up on row 24 I had deleted a row.causing the problem. Well spotted :)
Can't think of any other logic except it works for my purpose.
It is another way of performing a regression. If I could do it another simpler way I would.
The raise power method does provide a quicker and tidier solution
