Re: Expressions in table proc arguments

I can't even get the following to work:

scalar count = 3
adfstats.setfont(!count,3) +b

The error message is "Invalid cell range, invalid row value in !count". I get the same error message whether or not I use the "!"

Re: Calculation of standard deviation in stochastic simulati

Thanks, Gareth. I think we are saying the same thing (you are confirming what I thought). We are working on getting the confidence limits directly from the simulations (e.g.), picking out the 97.5th highest and lowest simulation) rather than using the calculated standard deviations.

Re: Calculation of standard deviation in stochastic simulati

Sorry, you will have to pretend I am especially dense here (not hard to do, really). What is the "normal" way? Is that the sample standard deviation for a given period just the standard formula calculated for the observations for all the simulations in that period? I just want to be sure I...

Calculation of standard deviation in stochastic simulation

When you do a stochastic simulation, you can get confidence limits and a standard deviation series. How are these calculated?

Re: Gompertz with 5 variables

I've also been working on estimating a Gompertz function, although with only three parameters (I think that's the word you want, not variables). You should be able to just specify the function in the "estimate" box of the equation object. For example, where x is your series: x =c(1)*(exp(c...
