當STM模型收斂時，R相對頻繁地崩潰。在30小時以上的評估會議後，參見下面的圖例。這發生在兩臺不同的計算機上，具有不同的數據大小。我一直無法確定導致這些崩潰的任何特定模式 - 因爲崩潰似乎不是確定性的。當STM模型收斂時，R崩潰
模型估計的設置是
# full
Year <- year(df$date) # year data from the environment
stmFit.full <- stm(out$documents, out$vocab, K = 0, prevalence =~ s(Year) ,
max.em.its = 150, init.type = "Spectral", seed = 300, verbose = T)
任何想法如何解決這個問題？
