Re: [R] Hausman test

[PAOLO PILI]

you are right about the 3rd line but it doesn't help me for my problem. I
remove the 3rd line but there is still the same problem:

Error in solve.default (dvcov):
   the system is numerically unique: reciprocity condition value =
1.63418e-19

[R] Hausman test

[PAOLO PILI]

Hello,

I have a problem with Hausman test. I am performing my analysis with these
commands:

[R] plm package

[PAOLO PILI]

Hello,
I got a problem using package plm. When I give the command

"grun.fe<-plm(Y~X1+X2...+Xn, data=data, model="within")"

I got this answer:

"Error: cannot allocate vector of size 289.7 Gb".

The database that I am using is not so big, so I don't understand to what
it refers to.
Can you help me, please?
thank you! have a nice day
