Hi all, I am running an -MNP- multinomial probit model package using R. It gives me the following objection instead of giving me the results: Erreur : impossible d'allouer un vecteur de taille 137.9 Mo (in english: cannot allocate a 137.9 Mb vector memory). I have already increased the memory size upto 2047Mb. This problem has been discussed in 2008 (archives) but no profitable answers were delievered. I am sending the programming and bit of data. Thanks in advance for your help. model<-mnp(choice~1+Asso+FP+BEV+IAA+CER+FrtVeg+Meat+Others+lnADH+lnTO+Emp+LT50inReg+lnEXinEU+lnEXoutEU+GDist+RET+WS+LT50SC+Others_hotel, base=4, n.draws=10000, burnin=2000, thin=3, verbose=TRUE, trace=FALSE, p.scale=1, coef.start=0, invcdf=FALSE, cov.start=1) AssoFPCGIAABEVCERFrtVegMeatMilkOilOtherslnADHlnTOEmpLT50inReglnEXinEUlnEXoutEUGDistRETWSLT50SCOthers_hotelchoice 00011000003,68897,55331,0000,00000,0000010004 00011000004,86759,01681,0000,00000,0000000014 00011000004,90538,98720,0000,00000,0000010004 00011000004,41888,03530,0000,00000,0000000104 00011000005,634815,19545,0000,69310,0000000101 10100010003,401214,59170,0010,00000,0000001001 00011000004,499815,12016,0000,00000,0000000014 11011000003,784213,49204,0000,00000,6931001001 10011000001,38638,86052,0000,00000,0000000002 Saqlain RAZA PhD Student [[alternative HTML version deleted]]
