Yep, sorry I forgot it :wistle: so the data are data frames with dim(8,1000) called DATA.ValX and DATA.ValY (part of the files attached as a xls file)
http://www.nabble.com/file/p18826528/ValX.xls ValX.xls http://www.nabble.com/file/p18826528/ValY.xls ValY.xls When I call the function "Test" to determine the formula, nls returns an error; there are no initial values for x and y whereas without the function "Test" and directly a formula; no error occurred in nls with the same DATA.
