abstract: 'We introduce improved methods for statistically assessing birth seasonality
  and intra-annual variation. The first method we propose is a new idea that uses
  a nonparametric clustering procedure to group individuals with similar time series
  data and estimate birth seasonality based on the clusters. One can use the function
  SCEM() to implement this method. The second method estimates input parameters for
  use with a previously-developed parametric approach (Tornero et al., 2013). The
  relevant code for this approach is makeFits_OLS(), while makeFits_initial() is the
  code to implement the same method but with given initial conditions for two parameters.
  The latter can be used to show the disadvantage of the existing approach. One can
  use the function makeFits() to generate parametric birth seasonality estimates using
  either initialization. Detailed description can be found here: Chazin Hannah, Soudeep
