Long description

The image starts with a square choice node labelled ‘approach’. The upper branch leads to a chance node labelled ‘stem node A’. From this leads a terminal node ‘5 years’ with probability 0.4 and ‘7 years’ with probability 0.6. The lower branch from ‘approach’ leads to a chance node labelled ’TD node B’. This has an upper branch leading to a terminal node 3 years with probability 0.3. The lower branch leads to a chance node labelled ‘3 years change? Node c’. This has an upper branch leading to chance node labelled ‘stem node d’. From this node there are two terminal nodes one for 5 years with probability 0.4 and 7 years with probability 0.6. The lower branch leads to a chance node ‘td node e’. This has an upper branch leading to a terminal node 2 years with probability 0.2. The lower branch leads to a chance node,with probability 0.2, labelled ‘3 years change? Node f’. The upper branch from here leads to a chance node ‘td node g’ which itself leads to 2 terminal nodes , 5 years with probability 0.4 and 7 years with probability 0.6. The lower node leads to a terminal node of 7 years.
