MSM modeling and transition rates in R
Greetings, I'm using MSM (mutli-state markov modeling) package to study the progression of fibrosis in U.S hepatitis C population. I find this is a very fascinating tool for an applied researcher like myself. I have a four stage progression only model without any absorbing stage, also assuming no misclassification error in the data for the time being. I also have a couple covariates in the model. so I get thes...

...et and available in R, learning a lot of theoretical things on about SVM esemble or Bagging method, I can't apply Bagged SVM esemble or Bagging method with R to my data because of many doubts and difficulties. This is the reason why I have decided to ask the expert for help. I have a sample of hepatitis data. The variable I would like to classify pattern recognition is class type in hepatitis data. I don't understand at all about the Bagging algorithm. I attach the following data and journal about bagging algorithm. What should I do ? could you help me?? Thank you very much for your attentio...

Adjunto tabla original Saludos cordiales #ESTO ES LO QUE
