The first method\nwe propose is a new idea that uses a nonparametric clustering\nprocedure to group individuals with similar time series data\nand estimate birth seasonality based on the clusters. One can\nuse the function SCEM() to implement this method. The second\nmethod estimates input parameters for use with a\npreviously-developed parametric approach (Tornero et al.,\n2013). The relevant code for this approach is makeFits_OLS(),\nwhile makeFits_initial() is the code to implement the same\nmethod but with given initial conditions for two parameters.\nThe latter can be used to show the disadvantage of the existing\napproach. One can use the function makeFits() to generate\nparametric birth seasonality estimates using either\ninitialization. Detailed description can be found here: Chazin\nHannah, Soudeep Deb, Joshua Falk, and Arun Srinivasan (2019)\n \"New Statistical Approaches to\nIntra-Individual Isotopic Analysis and Modeling Birth\nSeasonality in Studies of Herd Animals\".", "License": "GPL-3", "URL": "https://github.com/hchazin/SCEM, https://hchazin.github.io/SCEM/", "BugReports":
