PLM package PGGLS strange behavior
...owever, really like to estimate the random model instead. For me, the problem is reproducable using one of the examples from the PLM Jstatsoft article "Panel Data Econometrics in R: The plm package" (pp.19-20): data("EmplUK", package="plm") zz <- pggls(log(emp)~log(wage)+log(capital),data=EmplUK, model="random") summary(zz) Which for me results in the following warning: WARNING: Warning: 'random' argument to pggls() has been renamed as 'pooling' It then proceeds with estimating a pooled model. I've checked if PLM by any chance does...

Robust vce for heckman estimators
When using function heckit() from package ‘sampleSelection’, is there anyway to make t-tests for the coefficients using robust covariance matrix estimator? By “robust” I mean something like if a had an object ‘lm’ called “reg” and then used: > coeftest(reg, vcov = vcovHC(reg)). I’m asking this because in Stata we could use function heckman and then use vce option “robust”. We could do the

Anyone that know of DECT "client" for asterisk?
Anyone here that knows some hardware USB "client" (DECT) that can connect to a DECT base station and act as a "provider" in asterisk? Ergo, asterisk is the DECT handset, and connects to the DECT base station. Its also important that it also works with most asterisk-compatible devices, including for example raspberry's. The reason I ask, is that many providers in
