Hello! I was wondering if anyone could provide me with some guidance as to what weak instrument tests I can perform on a panel data random effects regression (xtivreg). Since it does not allow for the command "estat firststage" and gives me a chi-squared statistic instead of an F-stat (So I cannot apply the Stock-Yogo critical value). I am aware that xtivreg2 allows me to perform a variety of tests, however since I am using a random effects regression I need to estimate my IV-regression using xtivreg
