1. A method for condition monitoring of a machine, comprising:

  • obtaining a first set of data observations corresponding to a first pair of machine condition parameters, the first pair of machine condition parameters comprising two different machine condition parameters;

    determining a first correlation coefficient corresponding to the first pair of machine condition parameters based on the first set of data observations;

    determining a first p-value corresponding to the first pair of machine condition parameters based on the first correlation coefficient; and

    selecting at least one condition monitoring activity for execution from a plurality of available condition monitoring activities, wherein the selection of the condition monitoring activity is based on;

    at least the first p-value; and

    one or more defined selection rules that are,wherein the selection rule is defined as follows;

    in response to (i) the first pair of machine condition parameters including a related pair of variables and (ii) the first p-value being greater than a first predetermined p-value limit, orIn response to (iii) the first pair of machine condition parameters comprising an uncorrelated pair of variables and (iv) the first p-value being less than or equal to a first predetermined p-value limit,the selected condition monitoring behavior is a condition monitoring behavior configured to be executed in response to a detected fault condition.
