I decided to convert an old LR question to Maple 15 syntax and update my Maple T.A. questions. I have it working in Maple, but in MTA I get an error: "java.io.IOException: Maple computation error", I've eliminated lines until I found out the error is when I use Fit to solve for the equation. What am I doing wrong?

Thanks, Stephen

I define 8 x values, and calculate 8 y values with random residuals. Then I solve using least squares.

$x1=180;

I want to write some stats questions on forecasting. I would like to have a list which is a time series, and use Moving Average to derive forecasts, then calculate my errors, etc. I can do it all in Maple, but I don't know how to create a list in Maple TA. For instance, how do I create A in Maple TA's algorithm, where A is defined by:

A:= [seq(round(RandomTools[Generate](distribution(Normal(40,5)),1)), i=1..20)];

This is just a  list of some "sales figures" distributed approximately normally.

Thanks in advance

I found a used copy of Probability and Statistics Explorations with Maple by Karian and Tanis. I'd like to work through it, but the supplements come in Maple 6,7 and 8 versions and I use Maple 11. Can I load the supplement?

The version 8 one comes as a "package", stat.all, but I don't know what to do with it. The version 6 one comes as two files, a help file, *.hdb, which seems to load, and a stat.src file. I put the  src file in a directory which I added to libname, but I can't use "with" to call it.

Thanks in advance

I know how to solve a problem in Maple, but can't translate into Maple TA. I'm teaching elementary statistics, and want students to estimate a median using a cumulative frequency distribution.

In Maple, I randomly generate some intervals and frequencies. Then I define the CFD by giving the end points and the cumulative frequency, like;
(1) XY:= Array([[x0,cf0],[x1,cf1],[x2,cf2],[x3,cf3],[x4,cf4]]);

I'm using Maple TA with first-year business students.
