试试将“vnames=strvcat('cons','x1','x2','x3','x4'); ”改成“vnames=strvcat(‘y’,'cons','x1','x2','x3','x4'); ”

试试将“vnames=strvcat('cons','x1','x2','x3','x4'); ”改成“vnames=strvcat(‘y’,'cons','x1','x2','x ...

哦，好了，谢谢啊

感谢感谢

请问大牛，初学空间计量出现这个错误，怎么解决呀？谢谢！

>> results=ols(y,[xconstant x]);

您好，我也是这个问题Wrong # of variable names in prt_reg -- check vnames argument

T=11; % number of time periods
N=31; % number of regions
% row-normalize W
W=normw(W1); % function of LeSage
y=A(:,[4]); % column number in the data matrix that corresponds to the dependent variable
x=A(:,[5,11]); % column numbers in the data matrix that correspond to the independent variables
xconstant=ones(N*T,1);
[nobs K]=size(x);
% ----------------------------------------------------------------------------------------
% ols estimation
results=ols(y,[xconstant x]);
vnames=char('CXST','x1','x2','x3','x4','x5','x6','x7');
prt_reg(results,vnames,1);
sige=results.sige*((nobs-K)/nobs);
loglikols=-nobs/2*log(2*pi*sige)-1/(2*sige)*results.resid'*results.resid

LMsarsem_panel(results,W,y,[xconstant x]); % (Robust) LM tests

% The lm tests developed by Donald Lacombe
% see http://www.rri.wvu.edu/lacombe/~lacombe.htm

lm1=lmlag_panel(y,[xconstant x],W);
prt_tests(lm1);

lm2=lmerror_panel(y,[xconstant x],W);

lm3=lmlag_robust_panel(y,[xconstant x],W);
prt_tests(lm3);

lm4=lmerror_robust_panel(y,[xconstant x],W);
prt_tests(lm4);
