<div>Thanks for the quick reply. Tried that, but doesn’t make any difference — I still get 16 warnings and phase 3 doesn’t complete.</div>

<div>I wonder if I could produce the estimates with RSiena 1.1-212, and then update to 1.1-276 to use sienaRI()? Inconvenient, but better than nothing.</div>

Dear Mark,<br>
<br>
I am just guessing, but it could be that the message is coming from the<br>
new Dolby option. Try setting Dolby off by dolby=FALSE in<br>
sienaAlgorithmCreate (or sienaModelCreate).<br>

<br>
A small RSiena problem to resolve between World Cup matches: I may have<br>
stumbled upon a bug/version conflict/problem of sorts with RSiena. I'm<br>
estimating model with two sets of one-mode networks.<br>
<br>
The model can be estimated fine with R 2.15.3 and RSiena RSiena_1.1-212<br>
on my Mac running Mavericks, including using the parallel package. I've<br>
built RSiena_1.1-212 from source when downgrading to identify the<br>
potential problem, but it definitely worked back in April last year with<br>
the binary as well.<br>
<br>
In the meantime I've upgraded to R 3.1.0 and RSiena 1.1-232. Alas, the<br>
identical model now estimates fine until Phase 3 Iteration 1, then stops<br>
with the following warnings (any number from 16 to 25 warnings are<br>
generated):<br>
<br>
Warning messages:<br>
1: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
2: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
3: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
4: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
5: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
6: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
7: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
8: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
9: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
10: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
11: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
12: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
13: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
14: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
15: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
16: In cor(z$sf[, i], scores[, i]) : the standard deviation is zero<br>
<br>
etc.<br>
<br>
Updating RSiena to 1.1.276 changes nothing, i.e. I still get the<br>
warnings. I also get this when estimating the model without any<br>
covariates and three network effects.<br>
<br>
First, I wonder if this should lead me to question the results obtained<br>
with Siena 1.1-212. If not, I'd be fine just using the old version. The<br>
only advantage of course would be that with 1.1-276 I could use sienaRI,<br>
which looks extremely promising. Second, what do these warning tell me?<br>
The .out file looks fine to me.<br>
