SUMMARY

The discussion focuses on fitting a scatter plot with a regression line or best-fit line, specifically using the equation y=3/((x-3.75)/2.75)+9. Participants suggest adjusting the x-values to eliminate unwanted curves left of the asymptote, recommending a minimum x-value of 3. Additionally, they mention that combining the constants in the equation can simplify it. For further refinement of the fit, using Excel with the Solver add-in is advised.

PREREQUISITES
  • Understanding of asymptotic behavior in mathematical functions
  • Familiarity with scatter plots and regression analysis
  • Basic knowledge of Excel and its Solver add-in
  • Ability to manipulate mathematical equations for curve fitting
NEXT STEPS
  • Learn how to adjust x-value ranges in scatter plots to manage asymptotes
  • Explore regression analysis techniques in Excel using the Solver add-in
  • Study methods for simplifying mathematical equations in curve fitting
  • Investigate alternative regression models for better data fitting
USEFUL FOR

Data analysts, mathematicians, and anyone involved in statistical modeling or data visualization who seeks to enhance their understanding of regression techniques and curve fitting in scatter plots.

scatter plot needs a regression? or line best fitting it.

so far y=3/((x-3.75)/2.75)+9 is a pretty good fit

graph is attached

any suggestions on how to get rid of everything left of the asymptote?

Hello, I do not know how your calculator works. But if you set the minimum value of x so that the bottom left curve won't be displayed, it should work. Or are you looking for another equation to fit your data?
 
A few comments:

The 3 and 2.75 in your equation can be combined into a single number.

As kazumi said, changing the range of x-values should get rid of the unwanted curve. Looks like x_low = 3 should work here.

If you're looking to improve the fit, it can be done in Excel. You would need to have the Solver add-in installed.
