Incomplete Databases: Missing Records and Missing Values
2012Data completeness is an essential aspect of data quality as in many scenarios it is crucial to guarantee the completeness of query answers. Data might be incomplete in two ways: records may be missing as a whole, or attribute values of a record may be absent, indicated by a null.

This chapter applies our concept of total value to a discussion of the Australian TV crime drama series, Miss Fisher’s Murder Mysteries (ABC 2012-2015) one of Australia’s most successful TV exports. Miss Fisher has been sold to an unprecedented 247 territories in 179 countries and is available on a range of different networks and platforms thus ...

In this chapter the reader is introduced to the approaches used in the literature to tackle the presence of Missing Values (MVs). In real-life data, information is frequently lost in data mining, caused by the presence of missing values in attributes. Several schemes have been studied to overcome the drawbacks produced by missing values in data mining ...

We now assume that we have missing values in the second covariate. The observability of X2 is indicated by a random variable $$O_{2}:\begin{cases} & \text{1 if}\;\;X_{2} \;\;\textup obervable \\ & \text{0 if}\;\;X_{2} \;\;\textup unobservable \end{cases}\;\;\;\;2\dagger)$$ and instead of X2 we observe the random variable $$Z_{2}:=\begin{
