This database was designed on the basis of data provided by US Census Bureau
[http://www.census.gov] (under Lookup Access
[http://www.census.gov/cdrom/lookup]: Summary Tape File 1). The data were
collected as part of the 1990 US census. These are mostly counts cumulated at
different survey levels. For the purpose of this data set a level
State-Place was used. Data from all states was obtained. Most of the
counts were changed into appropriate proportions.
There are 4 different data sets obtained from this database:
House(8H)
House(8L)
House(16H)
House(16L)
These are all concerned with predicting the median price of the house in the
region based on demographic composition and a state of housing market in the
region. A number in the name signifies the number of attributes of the data
set. A following letter denotes a very rough approximation to the difficulty of
the task. For Low task difficulty, more correlated attributes were chosen as
signified by univariate smooth fit of that input on the target. Tasks with High
difficulty have had their attributes chosen to make the modelling more
difficult due to higher variance or lower correlation of the inputs to the
target.
