Thanks. Meant to say 'without' graphs. Not sure how to set this up? The values 0.8, 0.3, 1.7, 4.9, 6.7 against 1,2,3,4,5 when plotted in a graph give S=1.17, r=0.93. R is the value I require. Do I put the values 1,2,3,4,5 in A1:E1 and 0.8, 0.3, 1.7, 4.9, 6.7 in A2:E2? However, you state that FORECAST goes in E2?

There's a regression feature in the Analysis toolpack (which isn't, from what I remember, installed by default).

For your series of: 0.8, 0.3, 1.7, 4.9, 6.7 It returns the following array: 1.64 -2.04 0.372021505 1.233855745 0.866271579 1.176435294 19.43352601 3 26.896 4.152 For some of what you've posted: Slope 1.64 R2 0.87 Se 1.18 (Yes, for those values, using Linear Regression, R2 is 0.866272 or 0.87; not 0.93) But all kinds of statistics are available from LINEST.

I see you have an answer, but I was confused as to how you got these values from Excel's graph. The best I can do is plot the linear equation, and display the R^2 value of 0.866. (I don't see any option to display Standard Error S = 1.17 on the graph) Just to mention... =SQRT(RSQ(y,x)) 0.93 = = = = = = = HTH :>) Dana DeLouis

You enter it as an array. For example: 1. Select the range B3:C7 2. B3 should be the active cell 3. In the formula bar, enter: =LINEST(A1:E1,,,1) 4. To "confirm" the formula, hold down the Control and Shift keys while hitting <Enter>. Excel will then a. Enter the formula in the entire selected range. b.

I have two lines one linear (y=mx+c) and one exponential (y=c^bx) and they intercept each other. I believe it is possible to calculate where the lines intercept. Although I can do this by graphing the data, it takes time and allows for user error so a calculation would speed things along greatly. The problem: So for the first line using the equation y=mx+c the numbers for the 13kPa line are y=0.0021x+9e-16 And for the exponential line (y=c^bx) which we produce to using the myograph is y=0.0022^0.0046x (^=Exp) I know that the two lines intercept at 1613.

Hello, I have a dataset with a (straight) line fit to it (with regression value and everything). My question is how do I take line with a different slope and force fit it to my data and optimise this new fit (i.e. get a new, obviously smaller, regression value that's a maximum for the forced slope with my data)? It's sort of the opposite of forcing a line through zero, I think. Anyway, is it possible, and if so where do I go to find out how to do it? I think you have to do it the old fashioned way. Attached is a example. If you don't have 'Solver...' on y...

I have a project involving a hiking trail where I am trying to capture altitude on Y axis versus mile marker location on X axis. I can enter the data in adjoining columns and use the chart wizard but each mile marker value gets positioned along the X axis in uniform increments rather than an actual linear scale representation. In other words, mile markers 3.3 and the next mile marker (3.8) are the same distance apart on the X axis in the graphic representation as is marker 3.8 and the next one (12.5). This distorts the graphic representation of the actual linear distance between the...
