Is there any formula or method to calculate the relaxation time in drude method?

I am trying to calculate dielectric function of a half metal by considering intra-band contribution i.e considering Drude term. But to do this i need relaxation time as an input. However there is not specific resistivity of this compound available to deduce relaxation time from that. Now is there any other method to obtain relaxation time?
