With hierarchical clustering, outliers often show up as one-point clusters. Generate three Gaussian distributions to illustrate the effect of outliers. set.seed(656) x = c(rnorm(150, 0, 1), rnorm(150,9,1), rnorm(150,4.5,1)) y = c(rnorm(150, 0, 1), rnorm(150,0,1), rnorm(150,5,1)) ...

Consider the ranges A1:A3 and B1:B3 having the same size and only number values, as below =SUMPRODUCT(A1:A3,B1:B3) This will loop through the ranges, taking the product of values in the same row and summing them, returning 32 in this example. A1*B1 = 4 A2*B2 = 10 A3*B3 = 18

Consider the following ranges A1:A3 and B1:B3 as below =SUMPRODUCT(--(A1:A3="c"),B1:B3) This will first manipulate (A1:A3="c") into the following array A1="c" = FALSE A2="c" = FALSE A3="c" = TRUE Then apply the -- operator which converts...
