Kohonen’s self-organizing maps (SOMs) offer a promising alternative to PCA or UMAP for dimensionality reduction in the context of transforming non-image data into image-like representations. As an unsupervised learning algorithm, SOMs excel at converting high-dimensional data into lower-dimensional re...
Calculating covariance is a step in the calculation of a correlation coefficient. A covariance matrix is the basis of a correlation matrix. Normally correlation coefficients are preferred due to their standardized measure which makes it easy to compare covariances across many differently scaled variables...
Protein intensities without missing values in each cell type in intra-batch or inter-batches were used to calculate the coefficient of variations (CVs) in Excel (Microsoft office 365). Briefly, for intra-batches, the CVs were calculated using raw protein intensities inside each TMT set and then...
Background Including twins in randomised trials leads to non鈥恑ndependence or clustering in the data. Clustering has important implications for sample size calculations, yet few trials take this into account. Estimates of the intracluster correlation coefficient ( ICC ), or the correlation between ...
