% dimensions of the problem
N=46; % number of spatial units
T=6; % number of time periods
K=10; % number of explanatory variables, constant should not be included
m=63; % Value that indicates the period of time between the first observation in the sample and the moment the process being modeled has started in the past
M=2*m-1;
nobs=N*T;
利用matlab估计空间计量动态模型时，m=63是怎么来的，看不懂后面的解释，哪位大神给解释一下啊，感激不尽
