Dear friends,

After a long hiatus, here’s my new post (in Bahasa Indonesia) about matrix aggregation. This article is a collaboration between me and Ali Akbar Hakim (@osairisali) a fellow R user from Faculty of Economic Brawijaya University Indonesia. His major is Economic, and currently finishing his undergrad thesis in Input-Output Economic Analysis.

The article is currently under final revision, but the following are a few snapshot of it.
