SUMMARY

The discussion focuses on troubleshooting issues with the Ezyfit tool version 2.44 when fitting data. The user encountered NaN values in their dataset, which were removed, allowing for a fit to be made, but only for a single dataset. Despite successfully obtaining coefficients from Excel, Ezyfit fails to display R² values and does not fit data from both datasets simultaneously. The user seeks assistance in resolving these issues.

PREREQUISITES
  • Understanding of data fitting techniques
  • Familiarity with Ezyfit tool version 2.44
  • Basic knowledge of handling NaN values in datasets
  • Experience with Excel for data analysis
NEXT STEPS
  • Explore Ezyfit documentation for multi-dataset fitting
  • Learn about handling NaN values in MATLAB
  • Investigate methods to extract R² values from Ezyfit
  • Compare Ezyfit fitting techniques with Excel's data fitting capabilities
USEFUL FOR

Data analysts, MATLAB users, and researchers working with multiple datasets who need to troubleshoot fitting issues in Ezyfit.

Hello again,

Part of the problem is solved. There were NaN entities in the dataset. I removed those, now a fit can be made, but still, only through 1 dataset (see figure). How to put the fit through both??

Hello everybody,

I have a very large set of datapoints (about 500). I try showfit with Ezyfit tool, but it doesn't find a fit. I tried it with Excel, and this works. When I use the coefficients from Excel as first guess for Ezyfit, it plots the line but no information about R^2 is shown. What might be the problem... Additional problem is that the fit is only drawn for 1 dataset instead of the 2 together.

Hope somebody can help me

Grz Fr@nk
