How can I take only the variables with at least 5.000 observations?
Hello folks,
I need a hand here...
How can I take only the variables with at least 5.000 observations?
I have too many variables, thank you in advance.

There is an operator that does this function: Toolbox extension, Filter Attributes with Missing Values ​​operator. Simple and beautiful.

Hi @ceci_ro,
one approach would be using the Quality Measures operator. It calculates measures like missing values for each attribute.
Then "ExampleSet to Weights" from the Converters extension. Here you can select the attribute name and the measure you need (missing values).
Then "Select by Weights" with a copy of the original data and the weights you created. Weight relation = less equals, weight = e. g. 0.2 or whatever is appropriate for your data.
