This is NOT an S-LUS-specific question, just
letting you know so you don’t have to read any further if not interested
in anything non-S-PLUS.
There is a bit of a controversy in my office concerning
specific statistical terminology. I developed a set of logistic regression
equations that calculate the probability of lightning occurrence for the day
using a 15-year data set of several observation types. I stratified the
data into two sets: one was used to create the equations, and the other was
used to test the equations’ performance. In my field, these are commonly
called the ‘dependent’ and ‘independent’ data sets,
respectively.
One of us insists that the common terminology be used, the
other says the data sets should be called ‘development’ and ‘testing’
since that is what they are used for, and since the terms ‘dependent’
and ‘independent’ refer to other issues in statistics.
Any statistics expert willing to jump into the fray is
welcome. There is no money riding on this, only pride.
