Cubic Gradient Descent Package
R -
Does anyone know of a cubic gradient descent package? I found grad.desc()
but that only allows for a 2d function. I have 3 free parameters and thus
am looking for a 3d function.
Thank you,

Hidden Markov Models in R
...ions I run through the model is the feedback the
participant receives. Any help would be greatly appreciated. I think what
