(a) Dendrogram for cluster analysis of the 14 cryocooled insulin data sets introduced in §3.2 and (b) the spread of Rmeas values for random combinations of 2, 3, 4, …, 13, 14 data sets from the same group of data. The broken line joins the medians for all cases. Full lines join the inter-quartile range points for all cases. The empty circles represent Rmeas for all merged data sets found in the dendrogram. Seven out of 13 of them fall under the lower inter-quartile range line. However, 11 out of 13 fall below the median line. Although the selections suggested by BLEND do not perform as well as in the case of cryocooled thaumatin, still they can be considered to be very good.
