Create a 4 × 4 seed matrix for use with fungibleR (Waller, 2013, under review).
Creates a 4 × 4 seed matrix for use with fungibleR with a predetermined 4 × 1 Beta vector of standardized regression coefficients and a multiple coefficient of determination 𝑅² that is close to a predetermined 𝑅².
createRSeed(Beta = c(.1, .2, .3, .4), R2 = 0.3, tol = 0.5)
| Argument | Description |
|---|---|
Beta |
4 × 1 vector of standardized regression coefficients. |
R2 |
multiple coefficient of determination. |
tol |
tolerance for finding a 4 × 4 correlation matrix that has a coefficient of determination that is within |tol| units from the provided 𝑅². |
Returns closestR, an 𝐑 matrix that has the closest coefficient of determination to the provided 𝑅².
