Julia library for elastic functional data analysis

Build Status Build status Coverage Status

ElasticFDA ElasticFDA

A Julia package for functional data analysis using the square root slope framework and curves using the square root velocity framework which performs pair-wise and group-wise alignment as well as modeling using functional component analysis and regression.


This package can be installed using and is only currently supported on linux

(v1.0) add ElasticFDA

This package relies on two c/cpp optimization routines which will either compile with icc or g++. One of the libraries relies LAPACK and BLAS. The makefile will detect if icc is installed and use it, otherwise it will default to g++. If icc is detected it will use MKL as the BLAS and LAPACK implementation. Otherwise OpenBLAS is used/required.
