**The Mud Room** is where we can air grievances and joys, record and resolve issues, otherwise share experiences. It will also serve as our Vensim User Group (VUG?).
This is Bill. So far no word back from the Office of the General Counsel regarding the licensing of this software for use by an academic institution. Please stay tuned as I investigate whatever it is we might do to help this corporate review along. Thanks!
I've had an issue the past 2 weeks where all of my work/graphs are not showing in Vensim when I upload to the Workbook. Additionally, this week when I would update my equations, no changes would show on my graphs. Wondering if anyone had these problems and was able to fix them.
One way I have had to use is to create custom graphs. Their specifications are stored in the *.mdl file (it is ASCII text and visible to humans). Thus the graphs will persist.
Hi everyone, sorry for the melee and confusion surrounding workbook submissions! I turned off all the required question settings (this apparently is the default) and you should be able to submit your answers and up load files with relative ease now. Thanks for your patience!
Be sure to introduce yourselves to one another by replying to this post. Form teams of 2-3. For this week's sharing please answer these questions: What might I expect to learn from this course? Describe your experience of downloading VensimPLE, R and R Studio and building your first model? Who are my team mate(s)?
So, what is your definition of uncertainty? Let's consider a binary event about most anything we might have experienced. Some examples: bear or bull (about the future itself), investing or waiting (state of the markets), idling or operating (someone's car at an intersection), outage or normal (internet pranks), nasty or nice (waiting for a gift?), important or not (to or about someone or something), stressed or not (work, life), AB or AC (messages), etc. Our work this week is to forge an example of two separate ways in which the binary event might occur. One way with have a probability structure p, the other a different probability structure q, much like the Kullback-Leibler Divergence example in the reading. We will play them against one another as if they are two scenarios for the same binary event . Using our new-found tools for information entropy we will compare and contrast the two scenarios. Of course we will also interpret our findings by explaining it someone (her...
... That is the question. Cause and effect Is this different from antecedent and consequent? In statistics causation usually means the so-called correct prediction of the impact of some intervention. Is this reality though? We have been using System Dynamics for two weeks now to set up our cause and effect model. Then we used the model at the end of this week to generate rather shocky data by vibrating key parameters. We only drew ONE sample, ONE possible realization of the causal model! What we generated is very typical of so-called observational models. Does every realization simply come from the cause and effect? Or is there something else at work? Then we performed some light exploratory analysis with a 2 dimensional density contour map of a scatter plot -- now we are in the realm of cause and effect? or is this just antecedent and consequence? The question before the house: What does causation mean in business analytics? to the consumer of our analytical product?...
I've initiated an ITS ticket to install VensimPLE on remotely.manhattan.edu. Stay tuned!
