• Frequently Asked Questions
  • Can CurveExpert work with more than one independent variable?
  • How can I cite CurveExpert in a publication?
  • Why does CurveExpert suddenly erase my curve fits off of the ranking chart?
  • How can I increase the speed at which the graphs are updated?
  • Why does the chi-square reported in the Information dialog not match the standard error?
  • Why is there a huge number for standard error and correlation coefficient sometimes? Is this a bug?
  • As nonlinear regression progresses, the indicator for standard error (S) sometimes freezes, although the iteration counter keeps on ticking. What is going on?
  • A spline fit never matches my data at the points like it is supposed to, and sometimes has spikes and/or wildly oscillating tendencies. Is there something amiss?
  • Lagrangian interpolation sometimes bombs with a floating point exception. What gives?
  • I am using a Postscript printer driver, and my plots will simply not print in the orientation (portrait or landscape) that I tell it to. Is there anything that I can do?
  • CurveExpert saves the previous window position, and I don’t want it to. How do I turn this behavior off?
  • How do I obtain a debugging report to send to the author?
  • Why are grid lines drawn as solid lines (instead of dotted) on some computers?
  • The Internet links pointed to by the menu items under Help|Internet are now broken. Is there any way that I can change the addresses to the correct home page?
  • The file import dialog never appears, now that I need it. How do I get it back?
