Help: Tobit model (what does this mean?) No Argument found (ASAP)


I put this in with new data and it does not work. It worked last time I ran my tobit model on Final_Project_Data_2. These are the same variables from the last regression run.

thanks ~ EX_Tenn

vglm(Giv_Money.2 ~ log.GDP_Cap + Econ_Fr + NGOs + Lab_For + log.Fin_HH_Con + Gen_Ineq, tobit(Lower = 0), data = Final_Project_Data_3)

Error in environment(formula) : argument "formula" is missing, with no default
