SUMMARY

This discussion focuses on understanding the probabilities associated with the branches of a decision tree, specifically in the context of a linear programming (LP) problem. The user questions the absence of costs between links 3, 4, 5, 10, 11, 12, 13, and 14, seeking clarification on whether this is accurate. The probabilities are treated as given inputs, similar to the fictional costs depicted in the decision tree diagram provided in the link.

PREREQUISITES
  • Understanding of decision tree structures and their applications.
  • Familiarity with linear programming concepts and problems.
  • Basic knowledge of probability theory as it applies to decision-making.
  • Ability to interpret graphical representations of decision trees.
NEXT STEPS
  • Research how to calculate probabilities in decision trees using Bayesian methods.
  • Explore linear programming techniques relevant to decision tree optimization.
  • Learn about the implications of cost structures in decision-making models.
  • Investigate software tools for visualizing and analyzing decision trees, such as R or Python libraries.
USEFUL FOR

Data scientists, operations researchers, and decision analysts who are involved in modeling decision-making processes and optimizing outcomes using decision trees.

Could someone please show me how they arrive at the probabilities attached to the branches of this nodes.
Why is there no cost between on link 3,4,5,10,11,12,13,14 --------is this correct ?

The link to this tree is below

ps iwas of the opinion that this was an lp problem

It looks like the prob's are inputs (data) and you are to take them as given, just like the fictional costs stated on the diagram.
