Hey, how do I filter for operators that can handle missing values? i have a dataset that has a number of attributes with missing values which are not easily filled in, so was wondering what classifiers are available.

    In my experience, many operators cope with missing values but it can be difficult to know what effect their presence has on accuracy because the type of the missing value might introduce bias.

    You could use the "Filter Examples" operator and choose one of the options to filter out examples with missing attributes and compare performance with and without the missing values.
