Subject: Simulation numbers from a probability table
Dear friends,
If I have a table like this, first row A B C D ... are different
levels of the variable, first column 0 1 2 4 ... are the levels of the
"numbers", the numbers inside the table are the probabilities of the
"number" occuring.
A B C D ...
0 0.2 0.3 0.1 0.05
1 0.1 0.1 0.2 0.2
2 0.02 0.2 0 0.1
4 0.3 0.01 0.01 0.4
...
How can I use R to do the simulation and get a table like this, first
row A B C D ... are different levels of the variable, the numbers
inside the table are the "numbers" simulated from the probailties
table above?
A B C D ...
0 4 2 0
2 2 0 1
0 1 4 1
2 2 0 0
...
Thanks for help!
