In my investigations of ovule fates, I’ve needed to estimate regression parameters from discontinuous functions. A general term for such estimates is breakpoint regression. OFStatisticalEstimates.pdf demonstrates an approach using R for such estimates in the context of seed-ovule ratios. The code includes a mechanism for generating seed-ovule data that illustrate the types of functions that need to be considered.
