Hi Group, I have a code that does multiple regressions on a set of data. Depending on= the size and shape of the data I first do a regression, look at residuals,= subtract the worst data point and do the regression again. I've written th= is with a set of If statements so if the size of the data becomes too small= the next regression won't be done. This works fine for a single data set b= ut if I put it into a loop through multiple data sets then I run into troub= le. For example if the first data set goes through 5 regressions and the ne= xt data set only has enough data to go through 2 it takes the data from the= first data set for the last 3 which I don't want. How do I clear the data = after each pass through a data set. I've tried Clear[function1, function2,.= ..etc.]. I've tried UnSet[values,values]. So the question is once I've gone= through the loop how do I clear the values so the next data set through it= is not carried over. Thanks for any help. Cliff
