You will be able to: * Construct polynomials of up to 20 degrees from either real or complex roots. * Interpolate polynomials from points by Lagrange, Newton or Vandermonde methods and Quadratic or Cubic splines. * Perform Least Squares approximation by orthogonal projection, with or without QR factorization, or partial derivatives. * Learn about each of the algorithms with derivations, proofs, step by step demonstrations, and visual tools. * Have an option to enter data by either typing or tapping on XY plane, and save data sets between program runs. ## Polynomial Regression Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/e0/5e/2b/e05e2b9b-d66e-2403-6e5b-47bc5ccda34b/iPhone_15_Pro_Max_-_Home.png/1290x2796.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/3b/33/06/3b33066a-7eb4-1308-6c9e-f1b024f48626/iPhone_15_Pro_Max_-_Lagrange.png/1290x2796.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/86/20/8c/86208c41-d44a-7665-c7af-3028e38a40e9/iPhone_15_Pro_Max_-_Newton.png/1290x2796.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/24/e4/67/24e4671f-0f2e-e6a3-8f8f-82237459a763/iPhone_15_Pro_Max_-_CubicSplines.png/1290x2796.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/dc/a1/07/dca1075a-b45d-ce9e-2a41-38971b99766f/iPhone_15_Pro_Max_-_VietaEntry.png/1290x2796.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/2a/2c/21/2a2c2174-3d07-b99a-a514-9676575bec2e/iPhone_15_Pro_Max_-_ApproxEntry.png/1290x2796.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/e7/ed/8a/e7ed8af4-c32d-3d64-339d-98318d54cb42/iPhone_15_Pro_Max_-_InterpolSideMenu.png/1290x2796.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/b6/de/fa/b6defa6d-07a5-8b90-dc23-f26418798479/iPhone_15_Pro_Max_-_ApproxSideMenu.png/1290x2796.png) - [Screenshot 9](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/39/dc/4f/39dc4f4c-3dbc-7fb7-eff5-1c714f8a0aa2/iPhone_15_Pro_Max_-_VandermondeMatrix.png/1290x2796.png) - [Screenshot 10](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/b0/b1/f3/b0b1f3b8-15bf-6c00-422a-796d4699007c/iPhone_15_Pro_Max_-_ApproxPartDeriv.png/1290x2796.png) ## Polynomial Regression Discovered Keywords - polynomial regression ## Polynomial Regression Available In - [Angola](https://apptail.io/app/polynomial-regression-qnHv/angola) - [Bulgaria](https://apptail.io/app/polynomial-regression-qnHv/bulgaria) - [Bahrain](https://apptail.io/app/polynomial-regression-qnHv/bahrain) - [Brazil](https://apptail.io/app/polynomial-regression-qnHv/brazil) - [Canada](https://apptail.io/app/polynomial-regression-qnHv/canada) - [Switzerland](https://apptail.io/app/polynomial-regression-qnHv/switzerland) - [Chile](https://apptail.io/app/polynomial-regression-qnHv/chile) - [Czechia](https://apptail.io/app/polynomial-regression-qnHv/czechia) - [Dominican Republic](https://apptail.io/app/polynomial-regression-qnHv/dominican-republic) - [Ecuador](https://apptail.io/app/polynomial-regression-qnHv/ecuador) - [Estonia](https://apptail.io/app/polynomial-regression-qnHv/estonia) - [United Kingdom](https://apptail.io/app/polynomial-regression-qnHv/united-kingdom) - [Greece](https://apptail.io/app/polynomial-regression-qnHv/greece) - [Croatia](https://apptail.io/app/polynomial-regression-qnHv/croatia) - [Jordan](https://apptail.io/app/polynomial-regression-qnHv/jordan) - [Lebanon](https://apptail.io/app/polynomial-regression-qnHv/lebanon) - [Sri Lanka](https://apptail.io/app/polynomial-regression-qnHv/sri-lanka) - [Lithuania](https://apptail.io/app/polynomial-regression-qnHv/lithuania) - [Norway](https://apptail.io/app/polynomial-regression-qnHv/norway) - [Nepal](https://apptail.io/app/polynomial-regression-qnHv/nepal) - [Oman](https://apptail.io/app/polynomial-regression-qnHv/oman) - [Singapore](https://apptail.io/app/polynomial-regression-qnHv/singapore) - [Ukraine](https://apptail.io/app/polynomial-regression-qnHv/ukraine) - [Uganda](https://apptail.io/app/polynomial-regression-qnHv/uganda) - [United States](https://apptail.io/app/polynomial-regression-qnHv/united-states) - [Uzbekistan](https://apptail.io/app/polynomial-regression-qnHv/uzbekistan) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
