# Importing death table into markov transition

Hello.

I made a decision tree using markov model. for the transition to death of other causes I have a death table that gives the rates of mortality for each year of life. (ex 20years old, death rate is 0.009. 21 years old death rate is 0.008 etc). I currently have a table set up in treeage so that row 1 is mortality for cycle 1, row two is mortality for cycle two and so on. Each cycle is one year.

What do I put in the transition probability to pull from my table where each cycle it will take the probability one row down?. right now I tried tablename[_tunnel], but that doesnt seem to work.

Thanks in advance,

Kendyl

Belinda OrmeIn a Markov Model _stage is the counter for each cycle.

You do not create _stage you can just use it as you need. The first cycle is always _stage = 0. So if you have rows in your table, you will need to use: Table[_stage+1] to get the entry from the first row in the first cycle of the model.

Andrew MunzerI suggest you look at an example model in the Files View.

In that model, age is defined with a starting age plus _stage. This will increment age by 1 for each annual cycle.

Then the probability pDeathBackground pulls mortality data from a table based on the current age.

Note that the mortality data in the table is not accurate. Use your own mortality data.
