Hello everyone
I have a problem looking forward to your help.
I tried to fit my set of data:
-85 1.05263 0.30387
-75 1.35046 0.21091
-65 0.81008 0.13501
-55 0.88447 0.12766
-45 1.90095 0.17804
-35 3.59318 0.2339
-25 4.72954 0.25879
-15 4.15506 0.22435
-5 4.57592 0.3252
5 5.03697 0.34115
15 4.48785 0.22843
25 4.53401 0.25189
35 3.72175 0.23445
45 3.17097 0.22766
55 2.07167 0.19663
65 0.96694 0.14746
Using custom function: y=N*1/(x^2+102.55^2)^2)*((sin(x*Rc)/x)+(cos(x*Rc)/102.55)). My problem is that I cannot get the confidence band of fit using this function. Can you help me?
Thank you, |

Hi,
If you want to output the UCL and LCL (upper and lower confidence intervals of parameter), you can go to "Advanced" page under "Settings" tab of "NLFilt" dialog, and then check the "UCL" and "LCL" box under "Quantities: Fitting Parameters" section.
If you want to show "Confidence Bands" on your fitted curve, you can go to "Fitted Curves" page under "Settings" tab of "NLFilt" dialog, and then check the "Confidence Bands" box under "Fitted Curves Plot" section.
Please refer the detail information in this help page:

Thanks
