Many have contacted me to ask about how to access the data underlying my recent book co-authored with Al Stam and Cali Ellis, Why Leaders Fight. The data and replication information for the book is available now at my dataverse: https://dataverse.harvard.edu/dataverse/mchorowitz. This includes a new update to the LEAD dataset, completed after the book went to press, that we suggest you use if you want to use the LEAD data for your own research.
Also, to access the online appendix for Why Leaders Fight, go to: http://www.cambridge.org/us/academic/subjects/politics-international-relations/international-relations-and-international-organisations/why-leaders-fight. Click on “Resources”, which is 1/3 down the page, and search for the term appendix. The appendix includes the regression tables that underlay the research in the book, along with the codebook for the LEAD dataset. If you cannot find it for some reason, it’s in the dataverse referenced above
