are used to establish how a given network differs from a network in which ties have formed at random (see Lusher et al.
for counts model that appears in the next section uses a zero-inflated Poisson distribution, which requires that a non-zero term be added to the model.
We note that the choice of binary social relations is dictated by the ERGM
methodological framework, which can only presently deal with dichotomous data.
The Navy awarded a contract to the Raytheon Company in 1996 to develop and produce ERGM
, and the initial schedule called for the round to enter service in 2004.
Under development by SAIC and Lockheed Martin, the seven-foot long, 155 mm LRLAP will contain 24 pounds of explosives, considerably larger than the seven pounds of explosives in the 5-inch ERGM
The Navy has spent more than $100 million so far to develop a new 5-inch satellite-guided munition, called ERGM
, with a promised range of 63 nautical miles.
will be fired by the Navy's new 5-inch, 62-caliber Mod 4 gun, now being installed on Arleigh Burke-class destroyers.
The 5-inch ERGM
is fired from a naval gun and the 155 mm Excalibur from a howitzer.
