the Weight by Correlation operator can be applied only on ExampleSets with numerical or binominal label. It cannot be applied on Polynominal attributes because the polynominal classes provide no information about their ordering, therefore the weights are more or less random depending on the internal numerical representation of the classes.but I use Polynomial can calculates the weight of attributes.Why?

    I am not sure what your question is as you have correctly stated why polynominal attributes are not suitable for correlation analysis.  You can clear this error by using a Select Attributes operator before the Weight and just drop out any of the polynominal attributes.
