Hello all,

Stat49Pro+ and Stat48Pro+ ver. 3.0 will be available for the HP49G(+) and HP48G(X) calculators soon. In case you are unfamiliar with these products, a description of their capabilities is given below.

What I need is a few people who are familiar with basic and hopefully more advanced methods of inferential statistics who would be willing to try out the product and send suggestions. The HP48G(X) and HP49G(+) versions are both available for this.

If you are interested in previewing the product or seeing a detailed data sheet on the product, please send me an email at

guthjun...@charter.net.

Thanks,

Scott Guth

What's new in Stat49Pro+?

1. Arbitrary regression/least squares applications with

inference methods.

a. Linear regression with inferences on slope, rho,

expected/predicted y values.

b. Multivar-linear regression

c. Polynomial regression

d. Multivar non-linear regression

e. Many tests & confidence intervals for these applications

2. Better integration with the Data Manager. The Data

Manager can now be invoked from within any inference

application - just press the [Data] soft-menu key, and

enter your data. Once the data is stored, press the

[ImPrt] soft-menu key to import whatever statistics are

needed from your data set directly into your input form.

3. More ways to Describe multivariate statistical data (in

the Data Manager), including Mean Vector,

Variance/Covariance Matrix, and the Correlation Matrix.

4. Better inferential methods for normal-quantile plots.

The following gives an overview of the older features of the product:

Stat49Pro+ is a complete inferential statistics library written in

System RPL. Essentially all methods of descriptive and inferencial

statistics covered in a college level statistics curriculum are

computed by Stat49Pro+. Included is a data manager which stores sample data and sends statistics directly into input forms for the various inference applications. Some non-parametric tests are supported as well, along with normal probability plots and rank sums.
