Patch Release 4.1.2 is now available for Analytica and ADE

Jgrellier:

''12 Sept 2008''

Release 4.1.2 is now available for users for Analytica and ADE 4.1.0 or 4.1.1. Release 4.1.2 is a patch release, focused predominantly on bug fixes, rather than new functionality. If you have 4.1.0 or 4.1.1 installed, upgrading is fast and painless, and models that already work in 4.1.0 or 4.1.1 work fine without modification in 4.1.2. We recommend all users of 4.1.0 and 4.1.1 should install the patch release (we very very strongly recommend it for users of 4.1.0, due to some critical bug fixes).

You can view a list of what’s been fixed at [[What's fixed in release 4.1.2?]]. If you are downloading Analytica or ADE for the first time will automatically receive release 4.1.2. To upgrade from a previous 4.1.x release, simply download and run the installer for Analytica or ADE from [http://lumina.com/ana/support/download.htm http://lumina.com/ana/support/download.htm].

Array Abstraction

Jgrellier: Corrected links

'''Array abstraction''' is one of the most powerful features in Analytica. Although conceptually simple, Analytica modelers find that their mastery of [[array]] abstraction continues to improve over the course of years. Array abstraction provides many benefits:
* Flexibility: Easy to alter an [[index]], e.g., adding or deleting elements.
* Hyper-flexibility: Easy to adjust the dimensionality of a model, even late in the modeling process.
* Direct [[what-if analysis]] and [[parametric analysis]].
* Simplifies expressions, which increases transparency
* Reduces the cognitive load of the modeler, with dramatic productivity gains during model creation.
* Speed - Analytica is an array-based semi-interpreted language, but array operations, the bulk of the computation, occur in "native code".
* Representational Power: Any simple scalar function becomes a powerful array function when abstracted.
* Synergy with probabilistic inference: [[Monte Carlo method|Monte Carlo]] and [[Latin hypercube sampling|Latin hypercube]] simulation are accomplished in Analytica through array abstraction. The [[Run]] index (i.e., the simulation index), is just another dimension, and the [[propagation of uncertainties]] through the model is an instance of array abstraction at work.

Talk:Enhancement Requests for Analytica

Jgrellier:

I would suggest ordering the kinds of requests that people have under a few subheadings. Any objections? [[User:Jgrellier|Jgrellier]] 05:46, 28 November 2007 (PST)

Enhancement Requests for Analytica

2007-11-26T17:59:21Z

Jgrellier:

===Key for Level of Importance===
* Kind of cool *
* Valuable **
* Critical ***
* I can't use Analytica without it ****
* I'd pay x for it. $x

(If it's a modification of an existing feature, described in Ana wiki, you might want to add it to that description rather than here.)

===Requests===
Here's what I would really like to see added to Analytica:

* When learning to use Analytica, I often have to go to the manual, go to the index at the end, look at the page number for the command I want to know about, then get to that page in the manual (which is not the same page as that page in Adobe Reader). I would like it if there was a command reference that had links for all the commands to the appropriate manual sections. **

Good suggestion: In the meantime, you may find this useful. Open the PDF User Guide and show the "Function list" page (After "Appendices"). This lists all functions organized by functional groups (also control constructs, system variables, object classes, and parameter qualifiers). Click on any item to jump to the place in the User Guide that explains it. (Alex Graham)

* I would like to see a function that can do bootstrap estimates of variance for use with a small sample. I can't seem to find a way of doing that in Analytica. *

* Possibility to save models as image-files (PNG etc.): It is possible to save graphs as image-files but not views from models. Now we need to take a screenshot first and then convert it into image-file before we can add it to web-documents. ** --[[User:Jvillman|Jvillman]] 22:39, 27 June 2007 (PDT)

* An '''Undo History''' function, or at least the possibility of undoing more than just the most recent edit (as it seems to be at present). ** [[User:Jgrellier|Jgrellier]] 01:43, 26 November 2007 (PST)

* When viewing a graph and altering its '''Uncertainty Options''' it would be convenient if there was a '''Preview''' button, which would allow the user to see the result of changing these parameters. * [[User:Jgrellier|Jgrellier]] 09:59, 26 November 2007 (PST)
