I just checked out the data in the other post you displayed. If you can tell me what each of the columns mean:
ID Hersteller Typenbezeichnung Farbwerke Papierformat (Breite) (Max.) Papierformat (Höhe) (Max.) Druckformat (Breite) (Max.) Druckformat (Höhe) (Max.)
and explain the underlying process used to derive the data I can apply a statistical technique that imputes missing values using the variance - covariance structure of the data which leverages the correlations between the variables in order to predict the most likely value of the missings.
This seems like a quick, fun project, and I don't take on many small jobs like this anymore, but if you are ok with an upfront payment then I can do this for you.
Let me know. Cheers,
