SohailB Posted October 11, 2015 Report Share Posted October 11, 2015 Hey everyone! So, after much procrastination and headache, I think I've finally arrived at a topic for my Math IA. I want to use polynomial regression to find the equation with the lowest r^2 value modelling a road in my city. I'll then use the equation to calculate the length of the road, and compare it to it's real value (Which I'll calculate with an app on my phone). However, I feel that this topic might be a bit too easy for a math IA. What do you guys think? Is there any thing similar to polynomial regression for sqrt(x) or ln(x) equations? I ask because there was another road I found that I feel looked like those equations, but I don't know how to model them. The only curves I know how to model are polynomials that have x^2,x^3, etc. Thanks in advance Reply Link to post Share on other sites More sharing options...

kevG Posted October 16, 2015 Report Share Posted October 16, 2015 It's too simple, you just plot points on a graph and get the equation. It isn't much math cause you can pretty much do it on Excel... Reply Link to post Share on other sites More sharing options...
kw0573 Posted October 16, 2015 Report Share Posted October 16, 2015 Well if you can attempt to derive regression for ln(x) then definitely it's better than simply using polynomial regression! Reply Link to post Share on other sites More sharing options...

I was hoping I could have a look at your IA for reference. Please let me know if you don't mind. Thanks Reply Link to post Share on other sites More sharing options...
