R 中的 MSwM（马尔可夫切换模型）函数不起作用

Question

我正在尝试运行下面的函数，以便根据此链接创建马尔可夫切换模型。

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))

但是第二行代码给了我以下错误：

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

有人可以帮我解决这个问题吗？ 非常感谢。 我使用的数据在这里。

Answer 1

看来你的OLS规范太复杂了：msmFit中的olsY应该属于(g)lm或者"formula"类，所以就用这种方式重写你的第一部分代码

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