[Rsiena-help] Query about number of ties etc

[Jenny Long]

Hi all

My name is Jenny Long, I'm a PhD student working on a social networks
project in schools.

I'm currently revising a social network survey after running an initial
pilot. My results suggest that networks based on the top 5 friends (from a
list of ten) are as useful for predicting behaviour as networks based on
the full list of 10 friends based econometrics spatial filtering, spatial
lag etc analyses. I'm tempted to shrink my friend question down to the top
5 friends in order to limit the burden on students

Before I do that, I want to check whether using 5 friends to build a matrix
(over about 1000 students) would be an issue for using SIENA at a later
stage. Does anyone have any comment based on their own experience or their
knowledge of the mathematics that underly these models?

Are there any other critical features that I need to think about if I want
to apply SIENA to my longitudinal results? (I am familiar with those
outlined in the latest SIENA manual)

Thank you in advance for your help
