Solution 1: is it possible to use spreadsheet? OpenOffice or other?
It's really a matter of how much data we're talking about. It's pretty
easy (trivial actually) to make the value of any cell, the result of a
formula based on the contents of other cells - and then to extend that
to a row or column (i.e, the value of a cell in row C = f(cells above
I'm rather confused.
Another user Ron just say the opposite.
Suppose stock prices in an array (or table or database)
and annual earnings of 10 years in another array (or table or database)
to compute PE using average of last 3 years
is like writing a program
Can spreadsheet really do the job?
If you're talking a page or two of data (say 10 stocks, 10 data points
each, 2 dependent variables); and the data and outputs logically lay out
in a tabular fashion - then a spreadsheet is far easier than anything else.
On the other hand, if you're talking 1000s or 10s of 1000s of data
points, and complicated reports, then SQL and maybe a procedural
language on top of it, is a better way to go.
Maybe if you offered a little more information about the input data set,
the calculations, and what a report might look like - we could help you
select the easiest path.
In theory, there is no difference between theory and practice.
In<fnord> practice, there is. .... Yogi Berra
