Declare endogenous variables

Estimation ML/Bayesian estimation
1

Hi,
I am a new user of dynare. When I want to run a program it crashes! The message is as follows:

You did not declare endogenous variables after the estimation/calib_smoother command.
Undefined function ‘gaminv’ for input arguments of type ‘double’.

Error in draw_prior_density (line 72)
infbound = 1/sqrt(gaminv(1-10*truncprior, p7(indx)/2, 2/p6(indx)))+p3(indx);

Error in plot_priors (line 55)

dynare_estimation_1(var_list,dname);

Error in AP2 (line 141)

Can anybody help me please?

There seems to be a path issue. Matlab does not find the gaminv function, but it should be located in the matlab\missing\stats folder of your Dynare installation.

Thank you for your answer! But I do not think the problem is about the path.
I have added the folder “c:/dynare/4.3.3/matlab” and saved it in “set path” command, also in the command window I typed the correct path. Maybe the problem is related to how I’ve written the model! Could anybody help at all please?!
This is the model:

periods 1000;
var c k lab z;
varexo e;
parameters bet del alp rho the tau s;
bet = 0.987;
the = 0.357;
del = 0.012;
alp = 0.4;
tau = 2;
rho = 0.95;
s = 0.007;
model;
(c^the*(1-lab)^(1-the))^(1-tau)/c = bet*((c(+1)^the*(1-lab(+1))^(1-the))^(1-tau)/c(+1))(1+alpexp(z(-1))k(-1)^(alp-1)lab^(1-alp)-del);
c=the/(1-the)(1-alp)exp(z(-1))k(-1)^alplab^(-alp)(1-lab);
k=exp(z(-1))k(-1)^alplab(1-alp)-c+(1-del)k(-1);
z=rhoz(-1)+s*e;
end;
initval;
k = 1;
c = 1;
lab = 0.3;
z = 0;
e = 0;
end;
shocks;
var e;
stderr 1;
end;
steady;
check;
estimated_params;
stderr e,inv_gamma_pdf, 0.95,inf;
rho,beta_pdf,0.93,0.02;
the,normal_pdf,0.3,0.05;
tau,normal_pdf,2.1,0.3;
end;
var c k lab z;
varobs c;
estimation(datafile=simudata, mh_replic=10000);

It perfectly runs on my machine. Try adding not only the mablab folder but also explicitly the subfolder matlab\missing\stats

Many thanks for your reply. It works, but not completely! I could manage to get the first graph but not the second. The message is as follows:
