[R] Exponential Autoregressive time series model EAR(1)

2023-12-16 Thread Mohamed Ezzat 
Dears,

I hope that email finds you well.

I'm sending you this email to ask if there is any built in R code for
simulating the Exponential Autoregressive time series model of order 1
EAR(1).

So, please provide me with the code if the code already exists


Thanks in advance.

[R] Advice on starting to analyze smokestack emissions?

Kevin,
Sorry, was not aware of any access-restriction, but if you have problems and 
were interested in local AQ maybe

Bert, Tim, Karl and Richard, thank you all for your suggestions and
help.

I will try the R-sig-ecology list.

Karl, I wasn't aware of the RAQSAPI package, but it looked promising.
However, when I went to the source of the data it uses, the United
States Environmental Protection Agency’s (US EPA) Air Quality System
(AQS) Data Mart database, it looks like interactive access to the data
is restricted to those who can document a professional agency
affiliation. I don't have that. I'll work with the package to see if
this is true regarding obtaining the data through it. Thanks for the
suggestion.

Richard, the Canada study of crematoriums was very useful. Thanks.

Thanks, again, all, for your help.

-Kevin

You might also try the R-Sig-ecology list, though I would agree that it's not 
clearly related. Still, air pollution effects...?

Re: [R] Advice on starting to analyze smokestack emissions?

2023-12-16 Thread Kevin Zembower via R-help 
Just to follow up on this thread, I didn't experience any problems
accessing the air monitoring data with the RAQSAPI package that I
anticipated from the US EPA's Air Quality System (AQS) Data Mart
database website. I didn't have to qualify with an agency affiliation
at all, just an email address.

Thanks again, Karl, for suggesting this.

-Kevin
