Formula For S Shape Curve?
Dec 13, 2013I have a few dates and one Total value. I need to distribute this Total Value in such a way so I can get the same shape S curve (Date vs Value).

Derive Curve From Values Then Apply Curve To Another Dataset?
Jun 5, 2014I have a data set (Set#1) that consists of a positional rank (1-240) and a dollar value ($46-$1) for each positional rank. It's not a straight line set.
DataSet.JPG
What I need to do is take that curve and apply it to another data set (Set#2) (1-240) and assign a dollar value ($46-$1) to each positional rank.
A "corner cutting" way of doing it would be an Index/Match to simply carry over the dollar value from (for example) #45 from my Set#1 to #45 in my Set#2. This could work reasonably well with data sets of the same size, but mine aren't always the same size, so I need to apply the curve itself. I

View 5 Replies View RelatedFormula To Distribute A Value Along A Bell Curve.
Nov 19, 2008I'm trying to find a formula that would spread out a value amongst multiple cells along a bell curve. Say I have $x,xxx. I want to spread that amount out in a certain proportion, regardless of how many cells I'm spreading it throughout.
Say I have a $10,000 project. I want to be able to spread it out like a bell curve in the cells I choose. For instance, if it was a five month project it would be distributed as
January - $1,000
February - $2,500
March - $3,000
April - $2,500
May - $1,000
If I added another month it would change to
January - $833.33
February - $1,666.66
March - $2,500.00
April - $2,500.00
May - $1,666.66
June - $833.33
I already thought of manually adding percentages to each cell, but the formula needs to be dynamic.

Jun 23, 2009I have D4=0.42. I thought this formula =IF(D4<0.38,"Thin",IF(0.38<D4<=0.48,"Good shape","Bad shape")) was supposed to give me "Thin" for D4<0.38, "Good shape" for 0.38<D4<=0.48 and "Bad shape" for the contrary, but it only gives me "Bad shape" when D4 is clearly between 0.38 and 0.48.

Jan 24, 2014On the attached spreadsheet there is two irregular shapes. "Area1" & "Area2". I need to be able to determine which area the "ball" shape is located in. If the ball is in Area1 then "Multiply 8" gets the ball and "Multiply 9" moves to the blue cell "AH39". If the ball is in "AreaB" Multiply 9 gets the ball and "Multiply 8" runs to cell "S37"
I should be able to do the moving of the shapes using all the samples, its determining which area the ball is in is the problem.
In the real spreadsheet i will probably have around 10 different Areas.

Jan 28, 2009I'd like to apply a curve to a column of student exam grades and have the curved grades displayed in the adjacent column. Here is how I'd like to curve:
I like to make a linear function out of two coordinate pairs.
First Pair (x1,y1) = (Highest Exam Grade, 99) = (H,99)
Second Pair (x2,y2) = (Class Exam Average, Desired Exam Average) =(C,D)
Slope = (99-D)/(H-C) = m
Linear Function = Y-y = m(X-x) = Y-99=m(X-H)
Each student grade would = "Y" i.e. Y=m(X-H)+99

Calculate Best Fit Equation Of Curve
May 16, 2008I am trying to calculate the equation of a curve which best fits some data. On the x-axis is date and y-axis the readings. The curve is quadratic, so on the chart I am fitting a 2nd order polyomial and displaying the equation. To prove that the equation the trendline gives me is reasonable, I am applying the equation on the x parameter to get the y parameter estimate and looking to see the error between predicted and actual - see attached.
The equation and the output from it are clearly rubbish, even though on the graph the trendline is a reasonable fit - see attached. Has anyone any ideas why? I think it has something to do with using a date on the x-axis but no idea why. Is there a way to correct for this? I also tried using the following I to calculate the coefficients which came up with a reasonable forecast (although linest should only be used for linear data): =LINEST(C3:C15,B3:B15^{1,2,3})
Create S Curve Based On Dates
Apr 4, 2014I am working on Project Planning, I need to create the Progress curve for our Project based on Weight Factor every month.
I need to create the Plan and actual curve based on the dates defined in particular activities. Once the activity progress is calculated every month based on cut off date then it will sum product with corresponding WF to get the progress achieved every month. Presently I am calculating the values every month and pasting the values in Chart data every month. I had created the S Curve and attached here.
Now my objective is to automatically calculate the values for the entire cut off date at one time (From Project Start to End). i.e I don't want to do any manual work in the Chart. I will update only the actual Dates in the file, then the curves need to get automatically updated.
1) I don't want to calculate the progress for individual activities, I would like to calculate the overall progress directly.
2) When I change the Cut off date, then the previous values needs to become static.

Jul 11, 2013Here's the spreadsheet I am talking about : [URL]
So as you can see each row = one day divided in 2 cycles of 12 hours : every 12 hours the cat gets a new injection of insulin (the columns "U" being the number of units of insulin the cat receives)
Now I want to turn this sheet into two different curves that would look like these : [URL]
As you can see the first graph shows data based on days (x) and insulin dose (y), while the second curves shows data based on days (x), and blood glucose values (y). This is basically the only way we could clearly see how the cat's disease is evolving over a long period of time.
If he had just started to take all these values from his cat I guess it would be simple to do, but since he already has a lot of data entered in his spreadsheet, I was wondering if I could use this data (and not write each number in a new document), to make things a little more simple and to avoid mistakes.
