SUMMARY

The discussion centers on the challenge of removing the y-intercept from a linear fit equation using specific software. The user initially sought to adjust their equation from the standard form y=mx+b to y=mx, aiming to reduce percentage error in their data analysis. After successfully modifying the equation, the user encountered issues with correlation visibility, expressing frustration with the software's complexity compared to Excel.

PREREQUISITES
  • Understanding of linear regression concepts
  • Familiarity with software tools for graphical analysis
  • Knowledge of correlation coefficients and their significance
  • Basic proficiency in using Excel for data analysis
NEXT STEPS
  • Research methods for fitting linear models without an intercept in statistical software
  • Explore correlation analysis techniques in graphical analysis tools
  • Learn about alternative software options for linear regression analysis
  • Investigate best practices for minimizing percentage error in data fitting
USEFUL FOR

This discussion is beneficial for data analysts, statisticians, and researchers who are working with linear regression models and seeking to optimize their data analysis techniques without the influence of y-intercepts.

Hello, I am trying to remove the y-intercept from my linear fit with this software since my equation is y=mx and NOT y=mx+b, so I need to figure out how to remove the y-intercept so my data will have a smaller % error, because the intercept makes the slope larger than it should be. Any ideas how to do this? (yes I checked online, tutorial, help menu, etc)!

Edit: figured out how to do the y=mx, but now it doesn't show a correlation! This software is way worse than a simple excel..atleast less straightforward
