matlab做空间面板出现问题——NAN，怎么解决-经管之家官网！

我在用matlab做空间面板时，遇到几个问题，具体的操作如下：
权重矩阵（W1）和变量矩阵(A)在附件里
LM检验的命令为：
T=9; % number of time periods
N=55; % number of regions
% row-normalize W
W=normw(W1); % function of LeSage
y=A(:,[1]); % column number in the data matrix that corresponds to the dependent variable
x=A(:,[2:11]); % 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=strvcat('crste','PGDP','MIDU','EDU','PIN','PEX','PJIJIAN','CHENGZHEN','SZGX','TREAT','EFFECT');
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
% ----------------------------------------------------------------------------------------
% spatial fixed effects + (robust) LM tests for spatial lag and spatial error model
% fixed effects, within estimator
% demeaning of the y and x variables
model=1;
[ywith,xwith,meanny,meannx,meanty,meantx]=demean(y,x,N,T,model);
results=ols(ywith,xwith);
vnames=strvcat('crste','PGDP','MIDU','EDU','PIN','PEX','PJIJIAN','CHENGZHEN','SZGX','TREAT','EFFECT'); % should be changed if x is changed
prt_reg(results,vnames);
FE=meanny-meannx*results.beta; % including the constant term
yme = y - mean(y);
ee=ones(T,1);
error=y-kron(ee,FE)-x*results.beta;
rsqr1 = error'*error;
rsqr2 = yme'*yme;
FE_rsqr2 = 1.0 - rsqr1/rsqr2 % r-squared including fixed effects
sige=results.sige*((nobs-K)/nobs);
loglikfe=-nobs/2*log(2*pi*sige)-1/(2*sige)*results.resid'*results.resid
LMsarsem_panel(results,W,ywith,xwith); % (Robust) LM tests
% ----------------------------------------------------------------------------------------
% spatial and time period fixed effects + (robust) LM tests for spatial lag and spatial error model
% fixed effects, within estimator
% demeaning of the y and x variables
model=3;
[ywith,xwith,meanny,meannx,meanty,meantx]=demean(y,x,N,T,model);
results=ols(ywith,xwith);
vnames=strvcat('crste','PGDP','MIDU','EDU','PIN','PEX','PJIJIAN','CHENGZHEN','SZGX','TREAT','EFFECT'); % should be changed if x is changed
prt_reg(results,vnames);
LMsarsem_panel(results,W,ywith,xwith); % (Robust) LM tests
结果为：
Wrong # of variable names in prt_reg -- check vnames argument
will use generic variable names

本人是初学，还请哪位大虾指点一下，不胜感激！
