in reply to Estimating continuous functions

What kind of function (or curve, whatever) you fit depends on your data. Can you give us a sample data set so that we can suggest appropriate regressions? If it does not follow a set order, you might have to fit a very large polynomial to it and even then it may not be accurate outside the range of the data set -- since a piecewise function is still technically a function, fitting cubic splines may be enough. It depends on the data model and what you are trying to model. Either way, there are a lot of good web references on the requisite math, so with a better understanding of the problem space, we can give you better tips.

[tye]: I get an error string but no reason and no context. Like die "Could not read file.\n" but with a stack trace where all of the useful context is stripped.
[thezip]: Heya tye!
[tye]: hey, thezip!
[RonW]: Hi, tye, thezip
[RonW]: I see useless errors liek that from Perl programs, too.
[tye]: well, you certainly don't see strack traces with all of the values removed from Perl.
[thezip]: Howdy RonW. Not in *my* logfiles you won't!
[tye]: and I never claimed anything about 100% on either side.
[RonW]: Presumably because the coders didn't realize that die and warn will append line number and file when the message strings doesn'r end with a line terminator
