Weight by Gini Index

I noticed that this operator doesn't compute weights for all attributes (features) and omits some of them. My database had 1720 features and only 334 of them, the weights were computed. Any thought on why this operator works strange.

    Hi @mansour_ebrahim

    Please take into account that if you have many missing values in one attribute the Weight by Gini operator probably will ignore it. Check if the disappeared attributes have missing values and try to solve before to apply the Weight by Gini operator. 

    Best,

    Dear Cesar
    Thanks for your reply. No missing value (even one).
    Regards.
