I've read an article of Greene, Ceron, Schumacher and Fazekas which called The Nuts and Bolts of Automated Text Analysis: Comparing Different Document Pre-Processing Techniques in FourCountries.

In this article, the authors state that using stemming and stop word removing separately decreases the standard errors of scaling estimations (compared to no-preprocessed texts). But when using the combination of them, it increases it.

So can you help me why using these techniques separately it increases the precision while using the combination it the S.E. go higher.

Thanks in advance, J
