fit_mean {elasdics} R Documentation

## Fitting function for open curves

### Description

Fits an elastic mean for open curves. Is usually called from compute_elastic_mean.

### Usage

fit_mean(srv_data_curves, knots, max_iter, type, eps)


### Arguments

 srv_data_curves list of data.frames with srv vectors in each row. Usually a result of a call to get_srv_from_points knots set of knots for the mean spline curve max_iter maximal number of iterations type if "smooth" linear srv-splines are used which results in a differentiable mean curve if "polygon" the mean will be piecewise linear. eps the algorithm stops if L2 norm of coefficients changes less

### Value

a list with entries

 type "smooth" or "polygon" coefs coefs srv spline coefficients of the estimated mean knots spline knots t_optims optimal parametrisation
