q |
the column index of the parameter with respect to which to take the derivative. |
a |
The row index of the covariance matrix element to be computed. |
b |
The column index of the covariance matrix element to be computed. |
par.chol1 |
The vector of Cholesky parameters. |
Derivative of the function that transforms the cholesky parameters to the specified element of the covariance matrix, evaluated at the specified arguments.
