 French translation:régression polynomiale flexible Explanation:flex = flexible Polynomial regression extends the linear model by adding extra predictors, obtained by raising each of the original predictors to a power. Cubic regression uses three variables X, X2, and X3 as predictors. This is a simple way to provide a non-linear fit to the data. •Step functions cut the range of a variable into K distinct regions in order to produce a qualitative variable. This has the effect of fitting a piece wise constant function. •Regression splines are more flexible than polynomials and step functions, and are actually an extension of the two. The divide the range of X into K distinct regions. For each region, a polynomial function is fit to the data, however, the polynomials are constrained so that they join smoothly at the region boundaries or knots. These can provide and extremely flexible fit.

 Merci :)

neutral  Diego Delfino: This is what I thought as well (as posted in the discussione entry) did you find any result anywhere? I meant, french results, since I hadn't found any ghits.
