Directed dispute-year data (Gibler, Miller, and Little, 2016)
Description
These are directed dispute-year data from the most recent version (2.2.1) of
the Gibler-Miller-Little (GML) militarized interstate dispute (MID) data.
They are used internally for merging into full dyad-year data frames.
Usage
gml_dirdisp
Format
A data frame with 10,276 observations on the following 39 variables.
dispnumthe dispute number
ccode1a numeric vector for the Correlates of War state code for the first state
ccode2a numeric vector for the Correlates of War state code for the second state
yeara numeric vector for the year
midongoinga constant of 1 for ongoing disputes
midonseta numeric vector that equals 1 for the onset year of a given dispute
sidea1is the first state (in ccode1) on the side that took the first militarized action?
sidea2is the second state (in ccode2) on the side that took the first militarized action?
revstate1is the first state (in ccode1) a revisionist state in the dispute?
revstate2is the second state (in ccode2) a revisionist state in the dispute?
revtype11what is the revtype1 value for ccode1?
revtype12what is the revtype1 value for ccode2?
revtype21what is the revtype2 value for ccode1?
revtype22what is the revtype2 value for ccode2?
fatality1what is the fatality value for ccode1?
fatality2what is the fatality value for ccode2?
fatalpre1what is the fatalpre value for ccode1?
fatalpre2what is the fatalpre value for ccode2?
hiact1what is the hiact value for ccode1?
hiact2what is the hiact value for ccode2?
hostlev1what is the hostlev value for ccode1?
hostlev2what is the hostlev value for ccode2?
orig1is ccode1 an originator (1) of the dispute or a joiner (0)?
orig2is ccode2 an originator (1) of the dispute or a joiner (0)?
hiactthe highest level of action observed in the dispute
hostlevthe hostility level of action observed in the dispute
mindurthe minimum length of the dispute (in days)
maxdurthe maximum length of the dispute (in days)
outcomethe dispute-level outcome
settlethe settlement value for the dispute
fatalitythe ordinal fatality level for the dispute
fatalprethe fatalities (with precision, if known) for the dispute
stmonthe start month of the dispute (dispute-level)
endmonthe end month of the dispute (dispute-level)
recipwas the dispute reciprocated (i.e. did Side B also have a militarized action)?
numathe number of participants on Side A
numbthe number of participants on Side B
ongo2010was the dispute ongoing as of 2010?
versiona version identifier
Details
Data are the directed dispute-year data made available in version 2.1.1 of
the GML MID data.
I would caution against using the revtype variables. They are not
informative. They are however included for legacy reasons.
