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...

bagging algorithm
...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...

Estimados
Queremos con el paquete FactoMineR hacer este tipo de tabla de mortalidad
que lea los datos desde de una tabla csv
Realizamos lo que viene en la ayuda y es muy interesante, sin embargo cuando
mandamos a leer desde la tabla csv original de los autores
no hace el anĂ¡lisis porque algo falta y no nos percatamos de que es. Adjunto
tabla original
Saludos cordiales
