hi there, can anyone help me on the topic of frag polynoms?
i just heard of a friend of mine, that i could build in a functioon called fragpoly (he was talking of such a function in the 'stata' language) in order to improve my process of finding an optimal linear model. instead of trying a vast amount of transformed inputdata to find the best fit and then step backwards down to e.g. rank 5 in order to get a smooth curve, i could start right from the beginning with only very few but therefore very flexible funktions (litle similar to box-plot) which adopt themselve automaticaly to an optimal fitt and r-squered. can anyone tell me if such a flexible adoptive function also exists in r+? (i could not find anything on the r+ pages with these search words). waiting desperately for help joerg ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
