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.
