ARMA interpretation
http://www.talkstats.com/showthread.php/60715-ARMA-interpretation?goto=newpost
Wed, 06 May 2015 11:54:57 GMTHello,

I'm currently working on ARMA models and I'm trying to understand if the number of birds seen one year depends on the number of birds counted the previous years. I think I managed to fit the good model but I have problems with the interpretation... I didn't find many informations about it.

The model I chose thanks to ACF and PACF plots is an AR(1).

What do I have to look at to conclude ? Do you know a good document to learn how to interpret this ?

Thanks a lot, Victor

How can you determine the sum of squares total, sum of squares within and between, only knowing the mean, standard deviation and sample size...Hi

How can you determine the sum of squares total, sum of squares within and between, only knowing the mean, standard deviation and sample size of two groups e.g.,

group 1: mean 5.67 SD 3.055 sample size 3
group 2: mean 14.33 SD 2.081 sample size 3

Many thanks for any help and apologies if this is very basic stats!
