I am testing the effect of ESG rankings on effective tax rate and Hausman test shows me to do random effects (0.83) whereas I initially found fixed effects more plausible.

The code I am using is:
xtreg EffectiveTaxRate ESGCombinedScore ROAPercentage Leverage Size PropertyPlantEquipment Intangibles ROE, re

and

xtreg EffectiveTaxRate ESGCombinedScore ROAPercentage Leverage Size PropertyPlantEquipment Intangibles ROE, re robust

Both are missing wald(chi) values. All variables are numeric, double. How can I overcome this? My deadline is approaching and although I have been working since months, my dataset has just completely changed upon some clerical errors done by mapping.

Thank you in advance!
