我正在尝试重现我之前在 GeNie 中创建的网络，但我收到一个错误，即节点概率的某些条件概率分布的总和不等于 1。

   # create empty BN
    HazardNet <- empty.graph(nodes = c("scenario", "probability", "intensity", "hazard"))
    HazardNet

# dependencies
HazardNet <- set.arc(HazardNet, from = "scenario", to = "probability")
HazardNet <- set.arc(HazardNet, from = "scenario", to = "intensity")
HazardNet <- set.arc(HazardNet, from = "intensity", to = "hazard")
HazardNet <- set.arc(HazardNet, from = "probability", to = "hazard")
HazardNet

# define states - global distribution
lmh <- c("low", "moderate", "high") 
scenario.lv <- c("30 year", "100 year", "300year", "none")
intensity.lv <- lmh
probability.lv <- lmh
hazard.lv <- lmh

# create conditional probability tables
scenario.prob <- array(c(0.01, 0.03, 0.05, 0.91), dim = 4,
                        dimnames = list(scenario = scenario.lv))
probability.prob <- array(c(rep(1/3, 12)), dim = c(4,3),
                          dimnames = list(scenario =scenario.lv, probability = probability.lv))
intensity.prob <- array(c(0, 0.5, 0.5, 0, 0.3, 0.7, 0, 0.1, 0.9, 0.98, 0.019, 0.001), dim = c(3, 4),
                          dimnames = list(intensity = intensity.lv, scenario = scenario.lv ))
hazard.prob <- array(c(0, 1, 0, 0.5, 0.5, 0, 1, 0, 0, 0.5, 0.5, 0, 0, 1, 0, 0, 0.5, 0.5, 0, 0, 1, 0, 0, 1, 0, 0, 1 ), 
                     dim = c(3, 3, 4), 
                     dimnames = list( intensity = intensity.lv, hazard= hazard.lv, scenario = scenario.lv))

cpt <- list(scenario = scenario.prob, probability = probability.prob, intensity = intensity.prob, hazard = hazard.lv)
bn <- custom.fit(HazardNet, cpt)

我认为问题是节点场景？如果我没看错，我其他的cpt都很好。

我如何为具有 3 个状态的节点编码相等概率？
