Hello everybody.

I have seen that an integrated network analysis tool was a popular request for Stata14, so maybe some of you know better than me what are the current methods of network analysis.

I've found several user-written network analysis tools :

- netplot by R. Corten (see article in Stata Journal here : http://www.stata-journal.com/sjpdf.h...iclenum=gr0048 ), which seems convienient to draw network graphs from edges list, but does not compute any statistics (on vertices centrality degree, closeness centrality, etc..). It doesn't seems to allow weights on edges, nor color on the graphs.

- netsis (and related netsummarize) (also an article in SJ : http://www.stata-journal.com/sjpdf.html?articlenum=st0248 ), which gives the above mentioned statistics, either through a mata or stata implementation. However, the graphs on the articles are made via netplot, so no graphics here.

-nwcommands by Thomas Grund, which is still not mentioned on Statalist, and seems to do both graphs and statistics description, but the programming seems very special, with networks being entities apart, beside variables. Here is the website of the project (said "network analysis using Stata") : https://nwcommands.wordpress.com/ . The graphics seems to be even more complete than with netplot (possible to use colors and weighted edges).

Is anyone familiar with these tools? The last one in particular? Do you recommand to use netsis and netplot for respectively statistical analysis and graphical representation, or should I better learn the nwcommands specificities and use it for both analysis.

Ps : I know it certainly depends on what I'm aiming to do. So, basically I want to describe FDI network (host country being the vertices, linked if the same firm invested in both), and to see how the centrality, etc.. of this network changes with the considered firms (as I'd like to highlight firm heterogeneity in FDI strategies).

Edit : I forgot to mention the networkplot command from Chaimani et al (2013) (http://journals.plos.org/plosone/art...l.pone.0076654), which seems to do great graphs. Although Network Analysis is not much used in Stata, there is many independently developed command, so I'm a little confused on wich one to use.. Any advice?
