Not sure about exponential, but for the power trendline you can use =RSQ(LOG10(Known_y's),LOG10(Known_x's)) to calculate R^2. Order 3 is y=Ax^3 + Bx^2 + Cx^1 + D. Order 4 is Order 3 is y=Zx^4 + Ax^3 + Bx^2 + Cx^1 + D. great, thanks I tried with poly of order 3 (ax3 + bx2 + cx1 + x0) We can see that the equation that is being used is 18.2*x + 1870. Both of these approaches are far better at revealing detail than ismultiplying regressed curves. SO I will not be able to use this equation to get R2 for the polinominal or any other trendlines except of the linear and compare the R2 for different trendlines. That's how you can make different trendline types in Excel and get their equations. So it returns an array result (result in a range) without using the function ARRAYFORMULA. G A S REGULAR. Create multiple types of trendlines (linear, exponential, different types of polynomials, logarithmic, etc.) In this example, those will be columns. " =IF(A1==1,Show exponential trendline, IF(A1==2,show logarithmic trenline, show linear trendline)) ". In our case, the following formulas work a treat: a: =EXP(INDEX(LINEST(LN(C2:C13), LN(B2:B13),,), 1, 2)), b: =INDEX(LINEST(LN(C2:C13), LN(B2:B13),,), 1). To occupy less space in the chart, Excel displays very few significant digits in a trendline equation. Youcould then use it to get y-values for each of your curves ove a grid ofx-values, and go from there. Adding a Graph with Trendline Blue curve - google sheets trendline Red curve - the function rebuilt from trendline coefficients. E.g. In this case, the formula becomes: y = 1.24101325584000E+04x + 3.54956901100000E+09 Alternatively, use LINEST. However, understanding the complex processes and equations behind them is a tough cookie. 2) When I change it from "," to ";" and run the equations for the a, b1, and b2 for the polyonomial trendline, if I have negative values I take the message #VALUE, while when I only have positive values I get a normal result. You can add a trendline to a bar graph, column chart, line graph, or scatter chart. (b) Suppose you have n values altogether in A. Select the type in the Label drop-down box. When you purchase through our links we may earn a commission. If you select Polynomial, you can pick the degree. You may find an error in the equation in Scatter chart in Google Sheets. May I ask what does ^{1,2} and ^{1,2,3} stands for in Polynomial trendline formulas b2: =INDEX(LINEST(y, x^{1,2}), 1) and b3: =INDEX(LINEST(y, x^{1,2,3}), 1) ?

When I draw it on a chart and then add the best exponential trendline, both in Google Sheets and Excel, I obtain two different equations and R2. I forgot to say how to draw a linear trendline in Scatter Chart. So let's see how to customize the trendline. Original issue reported on code.google.com by asgallant571 on 2014-07-04 14:22:05 All reactions It is a pretty drastic approachto smoothing each of the curves, however, before doing your calculation.Might I suggest a less parametric approach or two? I wouldsuggest that any curve including all the points, or passing near all thepoints, might be considered, and the choice of which one necessarily issubjective. Further, otherweighting schemes are often employed, particularly where Bayesian estimationis concerned. "Tony"
