Analyzing attributes

Before we analyze the attributes, let's try to understand what we are dealing with. In total, there are eight attributes describing building characteristics, and there are also two target variables, the heating and cooling load, as shown in the following table:

Attribute	Attribute name
X1	Relative compactness
X2	Surface area
X3	Wall area
X4	Roof area
X5	Overall height
X6	Orientation
X7	Glazing area
X8	Glazing area distribution
Y1	Heating load
Y2	Cooling load
