Performing pair-wise comparisons of some pandas dataframe rows as efficiently as possible

For a given pandas dataframe df, I would like to compare every sample (row) with each other. For bigger datasets this would lead to too many comparisons (n**2). Therefore, it is necessary to perform these comparisons only for smaller groups (i.e.…

Is there a way to add cld to a combined ggplot?

I'm analysing a set of multivariate data, first comparing it to a control, then comparing the different treatments among themselves. The data can be found here. For the comparison with the control, I'm using ggpubr : ggbarplot(s1, x = "media", y =…

Generating a pairwise 'distance' matrix

I am trying to generate what I can best describe as a pairwise distance matrix from a data frame containing the distance between two neighboring points. These are not Euclidean distances, they are essentially the distance between points on a…

Calculate distance between every point of matrix with each other

I want to calculate the euclidean distance between every element of an n-channeled matrix to every other and then apply the function exp(-dist) to it. My matrix is MxN so the output must be (MxN)x(MxN). This is my code so far: MAX=M*N; A =…

How can I generate a pairwise probabilities matrix with mean and standard deviation fixed in advance?

I need to generate a joint probabilities matrix (80*80) with R such that the mean and the standard deviation of this matrix are fixed in advance. It's a symmetric matrix. The main diagonal elements are interpreted as probabilities p ( A i ) that a…
