However, Maple is versatile and we could create those procedures you mention.  Maybe a collaboration on a finance supplement is in order?  The latest comments added to the Post, Return Finance Package 139268 Wed, 07 Nov 2012 07:19:42 Z Christopher2222 Christopher2222 humm http://www.mapleprimes.com/posts/139264-Return-Finance-Package?ref=Feed:MaplePrimes:Return Finance Package:Comments#comment139272 thanx chris! the procedures themself are not difficult to write but it takes time! For example a non-generic percentage return of a matrix XX with 20 rows and 101 columns where time flows horizontally ie in rows. Matrix(20, 100, proc (i, j) options operator, arrow; 100*(XX[i, j+1]-XX[i, j])/XX[i, j] end proc) However, it is a strech by far to assume that people knows this or want to know it! The procedures also need to be generica ie work for column/row organized data. I would like to go from A to M as fast as possible without waisting any time hence these procedures should have already been written. I am dying you know! well so are you in another 60 years he he It is soo stupid that I am thinking it might be premeditated just to piss of some narcissistic economist!

I wanted to save the PC procedure ie PercentageChange (PC) in the finance module but Maple wont let me. Hence a created a new module called MyFinance (added to the help pages as well) with one single procedure PC. More procedures like first difference, log return etc can be added in an easy way later. I have uploaded the code as a Maple worksheet instead of copy/pasting code on MaplePrimes which is a pain in the ass for me. Let me know if their are any problems with the module :-) <a href="/view.aspx?sf=139284/446147/LL_80)_MyFinance_(Pe.mw">LL_80)_MyFinance_(Pe.mw</a> The latest comments added to the Post, Return Finance Package 139284 Wed, 07 Nov 2012 18:08:41 Z alex_01 alex_01 LibraryTools[WriteMode] http://www.mapleprimes.com/posts/139264-Return-Finance-Package?ref=Feed:MaplePrimes:Return Finance Package:Comments#comment139297 The builtin packages are readonly.  You can change that by using LibraryTools[WriteMode] to modify the library package to writeable.  Then can change back to readonly later after modification.  Although I would suggest not modifying the built-in libraries just in case it becomes broken and instead do as you have done already, by creating a new package MyFinance.  I meant to suggest Finance2 as a supplement name but that's easy enough to change.  Maple12 has a meager 12 commands under the finance package.  In Maple15 it exploded to almost 12x's that number to 140! (! not to be confused with factorial) simply awesome!  It could be pointed out to Maple to add some more commands if there are some that are believed to be missing.  The latest comments added to the Post, Return Finance Package 139297 Wed, 07 Nov 2012 22:11:27 Z Christopher2222 Christopher2222 humm http://www.mapleprimes.com/posts/139264-Return-Finance-Package?ref=Feed:MaplePrimes:Return Finance Package:Comments#comment139305 It is interesting you say 140 commands in the Finance package! That is quite inflated! That whats happend when a computer scientist get free hands with 0 input from an economist/finance person that is actually going to use this stuff! I would have traded the "AddHoliday" command for a percentage return command every time!   The latest comments added to the Post, Return Finance Package 139305 Thu, 08 Nov 2012 02:58:34 Z alex_01 alex_01 logical place http://www.mapleprimes.com/posts/139264-Return-Finance-Package?ref=Feed:MaplePrimes:Return Finance Package:Comments#comment139311 Yes, there were a few commands in there that weren't completely financially related.  However , a logical choice it was to have them placed in the finance package.  I haven't had a complete look at the Maple 16 finance package, as my native Maple platform is Maple12, but there are some fairly complex and interesting commands in there.  Even with the new statistics package there are still more commands that could be added.  It is not surprising that not all commands were included at the time.
