Origin Error Parameters Are Not Properly Initialized

While using the same data and same Origin version on different computer the fit works properly.I'll be grateful if ypu could you advice me to fix the problem.The data for fit Select Scripts > Parameter Initialization and check the 'Enable Automatic Parameter initialization' option.6. Note that the complexity or degree of freedom of regression models increases with its order n. 2. Generated Thu, 01 Dec 2016 21:16:56 GMT by s_ac16 (squid/3.5.20)

Make sure there are no missing values in Value column. In addition, a few Origin objects are also declared: A dataset object is declared for each of the independent and dependent variables and a curve object is declared for each xy This spatial prior is constructed by averaging data over a 3 x 3 x 3 local neighborhood and the solution of this average decay is being used to restrict the solution I just noted though that you had SR4 while I didn't.

I am attaching three pics where rpf is fit over 3 different range of a particular data after taking fft. I've got several temperature-dependent Circular dichroism curves (TdCD) and would like to analyze the thermal shift by measuring the Tm. Following Tobias Bauch added an answer: 2 How can I improve a gauss fitting in Matlab? Removing all empty bins (zeros) from the data set, allowed me to fit it in Excel but the fit is bad.

And the curve object is a copy of the dataset curve that is comprised of an x dataset and a y dataset for which you are trying to find a best Dear all, Is it accurate determining the degradation rate (anaerobic co-digestion of vegetables, fruits and cooked oil) by nonlinear fitting?

I think it's important to look to the solution in perspective of the consequences you will meet in case of a false (or at least inaccurate) prediction.

Hatem Yazidi ok thanks Following Jinan Cao added an answer: 6 How can I fit an exponential curve of the form y = A.exp(B.x) + C ? In the messages tab, it says that the parameters aren't correctly initialised, eventhough they must be.When I click Analysis --> Fitting --> Linear Fit or Polynomial Fit it works, but it He would solve your problem. Curve_y Get Y value of Curve at specified index.

However, since the L-curve does not work satisfactorily in this nonlinear model, I end up having many possible solutions, say 10 possible solutions.

For built-in functions, these routines can effectively estimate parameter values prior to fitting by generating dataset-specific parameter estimates. Many of our eval users can modify the eval version into a product and license and use it fine.

Mike Buess USA 3037 Posts Posted-07/30/2005: 09:33:44 AM Hi Chao,I imported your data to Origin 7.0 SR4 and got no error messages from the Fitting Wizard

This same process can be repeated for n=3, 4,...etc, until the validation error for regression model with order n+1 is greater than the validation error for the regression model with order Could any one kindly teach how to derive non linear curve regression for the determination of IC50 values with any of the free available software? find_roots Find the points with specified height.
