R 中的 MSwM（馬爾可夫切換模型）函數不起作用

Question

我正在嘗試運行下面的函數，以便根據此鏈接創建馬爾可夫切換模型。

olsY = model.matrix(persons ~ vocMean + ble + cal + weekday, model.frame(lm(persons ~ vocMean + ble + cal + weekday, data = data)))

msY = msmFit(olsY, k = 2, sw = rep(TRUE, 5))

但是第二行代碼給了我以下錯誤：

Error in (function (classes, fdef, mtable)  : 
  unable to find an inherited method for function ‘msmFit’ for signature ‘"matrix", "numeric", "logical", "missing", "missing", "missing"’

有人可以幫我解決這個問題嗎？ 非常感謝。 我使用的數據在這里。

Answer 1

看來你的OLS規范太復雜了：msmFit中的olsY應該屬於(g)lm或者"formula"類，所以就用這種方式重寫你的第一部分代碼

olsY = lm(persons ~ vocMean + ble + cal + weekday, data = data)
