Legendre polynomials application

Click For Summary
SUMMARY

The discussion centers on the application of 7th order Legendre polynomials for fitting coefficients L0 to L7 across various ANOVA classes. Roberto seeks guidance on back transformation methods to visualize these classes using the estimated coefficients. A response clarifies that expanding a function in terms of Legendre polynomials yields a polynomial function suitable for plotting approximations of the original function.

PREREQUISITES
  • Understanding of Legendre polynomials and their properties
  • Familiarity with polynomial fitting techniques
  • Knowledge of ANOVA (Analysis of Variance) classes
  • Experience with data visualization tools for plotting functions
NEXT STEPS
  • Research methods for back transformation of polynomial coefficients

I need some help. I fitted a 7th order legendre polynomial and got the L0 to L7 coefficients for different ANOVA classes. How can I get a back transformation in order to plot each class using the estimated coefficients?
Thanks to anybody.
Roberto.

Expansion of a function in terms of Legendre polynomials directly provides a polynomial function you can use to plot approximations to the function. So I'm not sure what you're referring to here.
