names of parameters from nonlinear model?
...name <- names( est$estimate )[v] )
}
}
derivs[[i]] <- deriv( as.formula( eqns[[i]] ), eqn.terms,
hessian=T )
jacobian <- attr( eval( derivs[[i]] ), "gradient" )
se <- sqrt( mse[i] * diag( solve( crossprod( jacobian ) ) ) )
2) decomopse the matrix (svd(crossprod(J)) or qr(crossprod(J)) ?
3) ask for help and see if there's a magic R function I can't find in the
code/faq/help docs/etc...
Sorry for the lame question but I'm not seeing an "elegant" solution...
Jeff.
