Hope that anyone can help! Thank you in advance, Rgards Jac ▼ Vieira, Luiz C.

[SIGMA+] is a standard function that collects n-column, single row vectors in Level 1 (RPN entry) in order to compose statistical data. This way, matrix (SIGMA)DAT is generated (something like):```[ [ 10% 0.2 ] [ 14% 0.1 ] [ 15% 0.3 ] [ 16% 0.2 ] [ 17% 0.2 ]]```After that, performing MEAN returns a single row matrix with the mean for each column. The HP28/48/49/50 series allow a n-th column matrix as data for statistics computations, and some functions apply to all columns, like MEAN and SDEV (Standard Deviation). Other functions/commands (like forecasting) need the target columns to be selected prior to execution (default goes to first and second columns). Hope this helps (and hope my answer is accurate; I have not a single manual nor a calculator to check names and procedures, though...) Cheers. Luiz (Brazil) Edited: 5 Sept 2006, 2:03 p.m.
