implement continuation methods for profiles #4

Open bbolker opened 7 years ago

bbolker commented 7 years ago

as far as I can tell, profiling is using the same starting values as the original call. This is inefficient and particularly bad when the likelihood surface is sufficiently weird that there are multiple modes for focal parameter values away from the MLE. Should implement

continuation method (i.e. use estimates from previous focal parameter fit)
linear extrapolation method

bbolker commented 7 years ago

This is at least partly done in 1bb009d0945d (at least the "naive" method), but a linear-extrapolation method might be even better. (Also, not enabled by default yet.)
