I can understand why you put that break; part in the code, but i cannot figure out why you used square root. I guess it was to reduce the number of iterations, but i can't catch the logic behind that. Besides,
Results The study found that the AL index, defined using clinical cutoffs after square root transformation, was a predictor of PI approximately 7 years later among the CPP samples (尾=0.448, 95% CI: 0.158, 0.737, p<0.01). The findings indicate that the AL index, defined using clinical ...
My old production code is long gone but I still have what I used for testinghere. It’s written in Rcpp (C++ with R bindings) and performs fairly well. It does not use sparse matrices (commitpending feature request in base library). We have to rewrite this in scala anyway so that mi...
We’re only interested in square matrices for this problem so I won’t go into detail about rectangular ones. To find the optimal rotation we first re-centre both dataset so that both centroids are at the origin, like shown below. This removes the translation component, leaving on the ...
