Figure 4. Simulation lineup: Tips Data, histograms of tip. Which histogram is most different?
Explain what makes it different from the others.
Figure 6 shows residuals plotted against the order in the data. Structure in the
real plot would indicate the presence of lurking variables. The plot of the real
data is embedded among decoys, which were produced by simulating from the
residual rotation distribution, as discussed in §3 and the electronic supplementary
material. Which is the plot of the real data? Why? What may be ‘lurking’?
(v) Leukaemia data: This dataset originated from a study of gene expression
in two types of acute leukaemia (Golub et al. 1999), acute lymphoblastic
leukaemia (ALL) and acute myeloid leukaemia (AML). The dataset consists of
