fit_200

The object <code>fit_200</code> is an object of class <code>brokenstick</code> that contains the
fitted broken stick model.

datasets

The broken stick model describes a set of individual curves by a
linear mixed model using a second-order linear B-spline. The main use of the model
is to align irregularly observed data to a user-specified grid of break ages.
All fitting can done in the Z-score scale, so non-linearity and irregular data
can be treated as separate problems. This package contains functions for fitting
a broken stick model to data, for predicting broken stick curves in new data,
and for plotting the broken stick estimates. For additional documentation on
background, methodology and applications of the broken stick model see
