Thanks @Justin Foster.
> This is quite interesting and exhaustive!
Yes, the book is quite exhaustive (and did I mention... free?). I find the topic fascinating personally.
> I have numerous questions I would like to ask you -
Sure.
> particularly in how you deal with constraints in your models as you employ a monte carlo method for inversions.
Right now you can make just about any variable for "properties" (single family homes, condos, townhomes, duplex, triplexes, fourplexes, apartments, industrial buildings, etc) change month to be any of the following:
1. Any set value you define
2. Add or subtract a "random number" to the then current value
3. Multiply or divide the then current value by a "random number"
4. Set the current value to be a "random number"
5. Set the current value to be a "random number" from a user defined defined normal distribution
You set the range of the random numbers (low and high) as well as a min and max for the end value (in case your fiddling would make it go out of range). So you could cap interest rates or vacancy rates or maintenance rates at mins or maxes to avoid weird results.
I tried to design it so that you could use it model the real-world as you see the real-world... not necessarily what *I* believe the real-world to be.
> How much control do users have over the ranges of these constraints???
A lot. A lot. A lot. Like... a real lot. :)
> or is it run as a completely open model?
Not sure what you mean by "open model". You can do some pretty freakin' crazy stuff with it if you want or just read the free book and see my analysis of 10 different, pretty "vanilla" models.
> Seems like quite a sophisticated way of looking at this
Yes.
> and as you mention, worthwhile considering its our future at stake.
Totally! This is serious stuff. You should not *just* hope and pray especially when you can do some planning and reduce some pretty obvious risks.
> Reading through your book now and will look into your planner.
Sounds great. Let me know if you have any questions.
Hope you enjoy the book!
There are some videos here that demo three scenarios as well that I recorded with @Chris Lopez as a guest for his podcast:
