Unweighted analysis
WebJan 4, 2024 · Principal coordinate analysis (PCoA) was conducted using unweighted and weighted UniFrac distances. A weighted pair group method with arithmetic mean analysis (WPGMA) and an unweighted pair-group method with arithmetic mean analysis (UPGMA) were used to perform clustering, from which beta diversity of bacterial community … WebApr 11, 2024 · 7.1.1 Unweighted Unifrac. Unweighted Unifrac is based on presence/absence of different taxa and abundance is not important. However, it is sensitive to the sequencing depth. If a sample is sequenced more than the others then it may have many OTUs (most of them unique) consequently affecting the unifrac dissimilarity estimation.

Type III sums of squares are tests of difference in unweighted means; However, there is an alternative method to testing the same hypotheses tested using Type III sums of squares; This method, unweighted means analysis, is computationally simpler than the standard method but is an approximate test rather than an exact test
WebJun 30, 2016 · An extensive comparison of the sample-weighted method (Hunter & Schmidt, 1990), and a newer unweighted method (Osburn & Callender, 1992) of meta-analysis is presented using actual data. Several of the advantages of the unweighted method predicted by Osburn and Callendar’s simulation research did not always hold in actual application. WebMultivariate analysis techniques (such as principal components analysis, cluster analysis, discriminant analysis) should generally be undertaken using unweighted data. A common area where such techniques are used is segmentation analysis, where the research aim is to identify groups of respondents who exhibit similar behaviours and/or attitudes.
WebSep 15, 2016 · The UniFrac distance metric is often used to separate groups in microbiome analysis, but requires a constant sequencing depth to work properly. Here we demonstrate that unweighted UniFrac is highly sensitive to rarefaction instance and to sequencing depth in uniform data sets with no clear structure or separation between groups. We show that … WebMar 13, 2024 · Independent Component Analysis (ICA) is a statistical and computational technique used in machine learning to separate a multivariate signal into its independent non-Gaussian components.
