What does "with gaps" mean?

for example:
Y
1 - 1 -0.400171165
1 - 2 1.481536087
1 - 3 NA
1 - 4 0.218367129
1 - 5 -0.785769492
2 - 1 -0.161817373
2 - 2 NA
2 - 3 -0.402386973
2 - 4 0.837537202
2 - 5 -1.366318013
3 - 1 0.591972882
3 - 2 0.490477648
3 - 3 0.409391605
3 - 4 NA
3 - 5 0.137311174

I'm confused - is Y a series or a vector?

[irulishka]

Y - seria with gaps.
I mast calcumate meanDV by formula @mean(@inverse(@cholesky(w))*y), but y with gaps? fnd afret useing this formula Eviews report me error message: "Size do not match in matrix function".
What I mast do?

What is W?

[irulishka]

W is symmetric weights matrix [15x15]

EViews drops the NAs when converting from a series to a vector automatically. You'll have to use the stomna command to first do the conversion yourself.
