Using constrOptim() function
...g this error:
Error in f(theta, ...) : argument "x" is missing, with no default
If I replace myFunction with myFunction(beta,x) I get this error:
Error in beta * feature_1[i, ] : non-numeric argument to binary operator
If I try myFunction(beta_i,x) I get:
Error in constrOptim(beta_i, mirror_lf(beta_i, x), NULL, ui, ci, mu = 1e-04,
:
could not find function "f"
Clearly, I don;t have a good understanding of how to use constrOptim() or
optim() for that matter. Any guidance? Thank you!
