That's correct - the missing values are distributed uniformly through all rows and columns.Christian wrote:AFAIK if you set missing value to 80% then randomly 80% of the data is missing. But that is not the true data source. Row 1-8 has 100% data and row 9 to 13 about 20%.
if you set the missing value to 80% then everywhere data is missing, not only node 9 to 13. At least this is what I interpret the Genie function missing value.
In your reply above you first refer to 'row 9 to 13', then 'node 9 to 13'. I'm not sure if you'd like to have missing values only in specified rows or columns - nodes are mapped to columns, not rows.
