Free Bootstrap Statistics Software - Trial Version

I was looking for a quick solution to doing Bootstrap or Bootstrapping statistics without writing a code. In times like this, I usually turn to R codes. In some lazy days, I use Excel macro. But now, I was determined to use a free software (at least a free trial) that does Bootstrapping stats.

My goal was to do bootstrap regression in my limited 20 samples and estimate properties of the beta coefficients.

I found one software that does it flawlessly - the S-plus. It is now own by TIBCO Software Inc (I thought it was owned by Insightful Corporation). You can download the free S-plus trial software here. If you download the S-plus, you get the chance to try the TIBCO Spotfire as well. Spotfire plots data with interactive visualization!

If you do not want a trial version, and prefer to use Microsoft Excel instead to do your Bootstrap, there is also an easy way to do it. Use the Excel Bootstrap add-in. The add-in enables bootstrapping from within Excel environment. Download and follow the instructions to install the plug-in.

For Bootstrapping Help, I found this guide (pdf) to help you interpret Bootstrap results.

Visit also the "Resample Library User’s Manual" for any of your the S-plus Bootstrap questions.
