[Traminer-users] p-values for sequential association rules?

[Aron Lindberg]

Hi,


When running sequential association rules I get several values in the output:


         Rules Support      Conf      Lift Standardlift   JMeasure ImplicStat   p.value
1 (I1) => (I2)      15 0.7142857 0.7482993   -1.1607143 0.45894146 -0.9770084 0.1642825
2 (I2) => (I1)      17 0.8095238 0.8480726   -0.4404762 0.20127953 -0.9770084 0.1642825
3 (I2) => (I3)      17 0.8095238 0.9373434    0.5193644 0.01626898  0.0805823 0.5321129


>From here I understand what support, confidence, and lift are:

However, what does the p-value mean? It seems to be highly and negatively correlated with the confidence, but at the same time I have many sequences with combinations high support, confidence, and lift that still are insignificant.


Hence: what does the p-value pertain to? Can the rules be meaningfully interpreted even with the p-value is insignificant?


Best,
ARon
