initial value for the measurement-error variance
initial value for the length scale at the top layer
initial value for the variance of the weights at the top layer
initial value for the smoothness parameter
initial value for variogram_logrange
initial value for variogram_logitdf
list of initial values for the initial weights (or the initial variational means of these weights). The list contains five values, one for the AWU, one for the RBF, one for the LFT (Mobius), and two for the affine transformation
