Hello All:
I've been labouring over a stata problem for quite a while now. I have
created a block diagonal matrix of instruments for each cross sectional
unit of my panel dataset, and would like to row join or stack them into
one large matrix. Each unit's instrument matrix is 8 columns and 5 rows,
and i would rather not have to manually join each unit's instrument matrix
by row as i have 448 units. Can anyone suggest a way to create my 5*448
row matrix other than
matrix ALL = [A1\A2....\A448}
thanks for all you responses in advance
