Missile Defenses

Description

Following a successful test of an anti-ballistic missile (ABM) in July 1999, many prominent U.S. politicians called for the early deployment of a full ABM system. The scientific community was less enthusiastic about the efficacy of such a system. This data set contains the success or failure of ABM tests between March 1983 and May 1995. Do these data suggest any improvement in ABM test success probability over time?
