title: Ruby Curve Fitting (logarithmic regression) package
body: <p>I am looking for a Ruby gem or library that does logarithmic regression (curve fitting to a logarithmic equation).  I've tried statsample (<a href="http://ruby-statsample.rubyforge.org/" rel="noreferrer">http://ruby-statsample.rubyforge.org/</a>), but it doesn't seem to have what I'm looking for.  Anybody have any suggestions?</p>
