Use to specify correlation matrix in convenient way
by giving entries of the upper triangular part.
Usage
cor_from_upper(n_var, entries = NULL)
Arguments
- n_var
Integer, number of variables (= rows = columns of matrix).
- entries
Matrix of correlation entries. Consists of 3 columns
(variable_1, variable_2, correlation) that specify both variables
and corresponding correlation in the upper triangular part of
the matrix (i.e. variable_1 < variable_2) .
Value
Matrix with user supplied entries.
Examples
cor_from_upper(2, rbind(c(1, 2, 0.8)))
#> [,1] [,2]
#> [1,] 1.0 0.8
#> [2,] 0.8 1.0
