Missing value
The value for an attribute is not known or does not exist. There are several possible reasons for a value to
be missing, such as: it was not measured; there was an instrument malfunction; the attribute does not
apply, or the attribute's value cannot be known. Some algorithms have problems dealing with missing
values.
