RE: Prime - Linear Least Squares Regression
Check the Statistics2Var app.
Enter your data colomn-wise like in NUM view.
switch so symbolic and choose your type of regression. You get your result in the fit window. (you have to switch to Plot to have the coefficients calculated it seems)
You can then use Statistics_2Var.S1 in different modules of the calc or copy/paste the result from Symb view in the 2Var-app.

But ifyou prefer the linear_regression command, you will propably not be able to type in the matrix as you think from the example:
Start a Matrix with Shift+5 (of course)
First entry is your first indepandant - 14 in your case. You can then hit the "," key to quickly add a colomn to the matrix. Fill in 0j;.2 there
To add a row put the cursor over +- and use "+" key.
go on...
Your are confused because you try to enter the Matrix as [[],[],.....[]] which is intuitive for computer users, but is seems to be a symbolic view for the online help..... In the calc there is the matrix entry mode. I would like to be able to use the text based entry aswell.


edit: I tried it: list works as desired. linear_regression( {{14,0.2},{21,0.5},...,{60,2.4}} )
