Question

我使用库'markovchain'制作马尔可夫模型时遇到问题。要制作markovchain图，您需要有一个transistion矩阵。如您所见，行总计为1。

但是，当我尝试制作markovchain时，我收到了这个错误：

> trans_matrix12 <- new("markovchain", transitionMatrix = trans_matrix)
Error in validObject(.Object) : 
  invalid class “markovchain” object: Error! Row sums not equal to one

谁能帮助我？

Answer 1

在创建markovchain时，由于数字容差，markovchain包中存在isse。我已经在github上托管的开发版本上推了一个补丁...你可以通过以下方式下载：

devtools::install_github('spedygiorgio/markovchain')

MarkovChain包错误
