ergm model, nodematch with diff=T
...d related packages. I generally
get interesting results, but when I run a model including sociality and
selective mixing effects for different groups, the model runs (and
converges) but I get a warning as follows:
mod <- ergm(network ~ edges + gwesp(0, fixed=T) + nodefactor("code") +
nodematch("code", diff=T)+ nodecov("vulnEVI") + absdiff("vulnEVI"))
Observed statistic(s) nodematch.code.5, nodematch.code.6, and
nodematch.code.8 are at their smallest attainable values. Their coefficients
will be fixed at -Inf.
The model nevertheless runs and converges and pr...

ergm
Dear colleagues,
I have another question, which, I think cannot be answered easily by the manual. What is the effect of including both nodefactor("Gender") and nodematch("Gender",diff=TRUE)) for the same variable in the model? Judging from the output (please see below), you cant have estimates for both for boys and girls forthe nodematch command, but I thought that the nodematch measures for boys and girls were not related. Does the nodematch command show...

multiple values for a factor using nodematch in ergm()
...u can offer.
I have a network object on which I'd like to simulate an ergm() using
{statnet}. Since the network object is large, I have not copied it here.
Each vertex has an attribute "language" which can take on integer values
greater than or equal to 1.
Is there a way to use the nodematch argument of ergm(), such that it
searches for any matches in the vertex attributes, rather than a 1-to-1
match?
For example, given
mat <- matrix(1, ncol=4, nrow=4)
net <- network(mat)
lang <- list("A", c("A","B"), "B", "C")
net %v% &quo...

ergm crashes
...ot;SchoolType",mSchType) where SchoolType can take six different/unique values.
Then, I run ergm models successfully using commands like the following:
m3 <- ergm(ng ~ edges+nodefactor("Gender")+nodefactor("SchoolType"))
But if I try to run a command with the parameter nodematch, R crashes with no excuses and no error messages (I use windows Vista and the latest R version and all packages are fully updated). I use commands (and they crash) like the following:
m3 <- ergm(ng ~ edges+ nodefactor("Gender")+ nodematch("SchoolType"))
Can anyone help me wi...

Matching multiple nodes with a regular expression
...s, each of which has a hostname consisting of
the cluster type and a unique id (e.g. tc-dev-1, mysql-stg-3, etc).
I''ve been merrily adding each node by hand to puppet but being
naturally lazy I wondered if this could be done with a regular
expression instead, something along the lines of:
nodematch "tc-liv-\d+.*?\.ac\.uk" { .... }
which would then map all matching nodes to that default configuration.
Adding the code to do this doesn''t seem to be a unsurmountable
problem, but I''ve only just started reading through the source so
perhaps I''m wrong. Does this...
