In contrast, real data science would use a rich data model based on a comprehensive, relevant data set to provide accurate, actionable and highly valuable insights.
In addition to simple searches based on a single data field, advanced queries can be built by combinations of relevant data set specific key items with restrictions on queries by way of constraints.
For each outcome, risk scores were classified as low, medium or high: the cut-off that would classify a child as 'High risk' was chosen based on the prevalence of the outcome among overweight children in the relevant data set.
Before any statistical analyses were made, all relevant data sets were first tested for normality using the D'Agostino-Pearson omnibus test.
The insilicoDB (4) project provides many curated gene expression data sets; however, it is not a focused resource in terms of retention or quality assurance of clinical annotations, or retention of all relevant data sets and clinical variables for any one cancer type.
A more relevant data set might have been early fluid requirement during the first 12 to 24 hours after admission.
Furthermore, a new procedure of selecting the relevant data set is proposed.
Comparisons performed on each relevant data set returned a P value of <0.001 in each case (four tests total, bootstrap and best trees tested on both data partitions) which suggested that the two data sets contained different phylogenetic signals.
Of course, not every relevant data set can be accessed through web services; a list of web services currently available is provided by the EMBRACE Registry (Pettifer et al. 2009).
So if we think about household incomes, then we have an upper class of plutocrats who do not really appear in the relevant data set and who by the way pay very little tax because of their systematic use of the tax avoidance industry, a middle class of those in the top decile of households we know about, although they also often legally avoid tax, and the rest of us below them.
