Binarized version of the California Housing Dataset
This dataset was obtained from Luis Torgo's collection of regression datasets. It was binarized to serve as the original, unprocessed date for the California Housing dataset used by:

## Description:
This is a dataset obtained from the StatLib repository. Here is the included description:
S&P Letters Data
We collected information on the variables using all the block groups in California from the 1990 Cens us. In this sample a block group on average includes 1425.5 individuals living in a geographically co mpact area. Naturally, the geographical area included varies inversely with the population density. W e computed distances among the centroids of each block group as measured in latitude and longitude. W e excluded all the block groups reporting zero entries for the independent and dependent variables. T he final data contained 20,640 observations on 9 variables. The dependent variable is ln(median house value).

The file contains all the the variables. Specifically, it contains median house value, med ian income, housing median age, total rooms, total bedrooms, population, households, latitude, and lo ngitude in that order.
