...e es lo que comentas, en matemáticas no se suele llamar bucketización (este término se emplea más en informática) sino datos agrupados. Pero la idea es la que tu mismo dices. Respecto a las gráficas que has puesto, me han aclarado mucho sobre el tema, gracias. Si realizo lo mismo, por ejemplo con nbucket=1000 sigo obteniendo un p-valor de 1. Es decir, que casi le pongas lo que le pongas se obtiene un p-valor de 1. ¿Qué otros test de contraste de hipótesis me podrías recomendar? Porque igual ocurre lo que tu bien has dicho de que el test de K-S no es precisamente el mejor para este caso. Un salud...

I have a dataframe called "data" with 5 records (in rows) each of which has been scored on each of many variables (in columns). Five of the variables are named var1, var2, var3, var4, var5 using headers. The other variables are named using other conventions. I can create a new variable called var6 with the value 15 for each record with this code: > var6=var1+var2+var3+var4+var5

...in MultiSource/Applications. Second: I've also tested lookup3 hash, and its use generated 0.1% more collisions, compared to SFH. These results were a bit surprising for me! Number of hash table resizes is independent of used hashing algorithm, because hash table grows when 'nentries > nbuckets * 2'. Gregory

Thanks for doing the evaluation! It sounds like we should stay with SFH. In addition to fewer collisions, it is cheaper to compute. -Chris
