1. A method for analyzing variables influencing a combustion process in a combustion chamber, comprising:

  • training a statistical model using predetermined values of influencing variables;

    altering parameters of the model such that the model describes the combustion process; and

    determining the influence of the altered parameters on the combustion process,wherein the model parameters are weights of the model,wherein the variables are analyzed by a pruning method and a pruning of the model parameters is performed during the pruning method, andwherein the pruning method comprising;

    representing each of the influencing variables by a node,providing a link between each of the nodes,determining a zero order statistical independence and dependence between two of the nodes,removing the link between the two nodes when a zero order statistical independence is determined between the two of the nodes;

    removing a link between a first node and a second node based on a first order statistical independence such that the link between the first node and the second node is removed when the first node is linked to a third node and the second node is linked to the third node.
