What is the relationship between the product function and the concept of permutations with repetitions?

from itertools import permutations,product,combinations_with_replacement colours = [‘r’,’g’,’b’] y = list(product(colours,repeat =2 )) x = list(combinations_with_replacement(colours,2)) print(y) print(x) I understand permutation of a set of objects is an ordering of those objects. When some of those objects are identical, the situation is transformed into permutations with repetition. >Solution : This may provide some insight: colours =… Read More What is the relationship between the product function and the concept of permutations with repetitions?

Vectorised argument for a function in R. The function gives out multiple data frames, whereas I'd like it to output only one

I’d like to compute trimmed mean for each trimming proportion alpha, and then see which trimming proportion gives the minimal variance of the trimmed means, when Bootstrap simulations of size N=200 are applied. The problem that I have, is that when I try to create a data frame of column1 = mean and column2 =… Read More Vectorised argument for a function in R.

Duplicating values from matrix next to the original value in R

I have a matrix including simulated data. The data concern a repeated measurements situation, and for one variable I would like to duplicate the simulated values. The current matrix looks like this: [,1] [,2] [,3] [,4] [,5] [,6] [1,] 1.647 1.125 0.559 1.614 1.578 0.377 [2,] 0.555 0.395 1.090 0.896 2.135 1.184 [3,] 0.269 2.022… Read More Duplicating values from matrix next to the original value in R
