Generate the initial values for fitting shifts with a model of the 5-parameter logistic function.
prepareInitsLM(batches, ref.batch = 1)a data list contain the following elements,
inits, the initial values for the standard curves of all the plates
ref.ibatch, the index of the reference batch
This one is specified by the input ref.batch.
ref.irun,the index of the reference run
ref.index,the index of the reference line in the order
of the inits vector
list of elisa_batch data
numeric the index of the reference batch. It is 1 by default.
This is a more complicated way to prepare the initials for shifting.
