Misspoke earlier though. For the Beta coefficients, a=b>>1 gives a centered Normalish distribution around 0.5. If you want something flattish, but avoiding extremes, you'd want 1<a=b<2.

Anyway ... I can replicate this with a simpler example, so no need. Will explore a better boundary reflection approach.

Oops - missing data.vdfx.

What param are we looking at in the histogram?

I guess the likelihood was also uniform over this experiment? Reflecting off the boundaries is tricky in multidimensions, but we could probably improve on this behavior. In the short run I don't have a good solution though. A couple possibilities would be to use the logistic transform on the paramet...

I think what you're seeing is correct.

The stock Cena is constant because the flow Zmiana ceny is 0. That happens because Cena = Cena rynkowa.

I find the table tool most useful for diagnosing problems like this.

Exclamation point works for comments.

I think the rules are much like those for .cin files,

If you look at a .out file (which can be reused as a voc), you'll see comments like:
:COMSYS After 22610 simulations
Just the :C should be sufficient.

Spaces should be OK.

A quick way to do this would be to vary the noise seed in Synthesim, changing the run name each time. You can do this one of the following ways: A. Create a variable called NOISE SEED, with value 1 (or any other integer). Set the range to something like 1 ... 1000 and the interval to 1. In your rand...

You should be able to replicate the error manually. Just do a run with the first reported problem, manually changing additional cooling tariff kwh as shown.

When you choose "simulate 1 param +/- 10%" it creates ordinary runs that will appear in the dataset control, on plots, etc.

The thread affinity warnings are benign. It just means the operating system declined to assign requested threads. Presumably this is Windows, where thread management is not as good as Linux. It won't affect results. The crash might be related to the floating point errors in the model. Did you submit...

Surely S2A = Sensitivity2all

I think Aliakhavan89 is on the right track. However, it's impossible to give a precise answer without more information than the chart provides. What are the TIME STEP and SAVEPER? Presumably 12000 hours from eyeballing the chart? What is the equation for end use efficiency? A step * exponential? Or ...

SUM is definitely the summation operator Sigma. The exclamation point is not useless; it is necessary in cases where you'd like to sum over a subset of the dimensions belonging to the right side. I would write the equation in your image with something like the following: n : n1, n2 s : <something> a...

Looking at the model may not be required, but I'm not sure an answer can be given from the material here. What you're showing seems syntactically valid, so the problem may be somewhere else. What are the definitions of h and pressure number? What is on the left side of the sum expression? Is h the e...

Probably not, but you could modify your flow equations to do the same thing. We'd have to have a concrete example to comment on.

#2 has the Simulate>Based On setting active, which might change the lookup.

Some of this will change with the new equation editor soon.

You can use DELAY FIXED for this: Previous GDP = DELAY FIXED( Current GDP, one year, Current GDP ) ~ $/year one year == 1 ~ year In continuous time, you can use the SMOOTH function, i.e. Previous GDP = SMOOTH( Current GDP, one year ) ~ $/year You can also use the TREND function to compute a fraction...

Is the run "current" the first loaded dataset?

On the other hand, if you're interested in stochastic extinction of a disease in a small population, integer values may matter.

It's impossible to answer these questions in general; some specifics of the question to be answered must be known.

Like Forrester, I think that discrete quantities are rarely a good place to start. Things that are theoretically only available in integer quantities either don't matter, or have qualifications. For example, people are certainly available in integer quantities. But what about the work-equivalent of ...

Try this instead ...
You can also use SAMPLE IF TRUE for this (though I think it's not available in all versions).
