REML estimates can be obtained using the Direct-Inversion Newton-Raphson and Direct-Inversion Average Information algorithms for the problems r x r (r being the number of records) or using the Henderson-based average information algorithm for the problem c x c (c being the number of coefficients to estimate). Spatial models can also be fitted using the two-dimensional spline functionality available.\n\n## Installation\n\nYou can install the development version of `sommer` from GitHub:\n\n``` r\ndevtools::install_github('covaruber/sommer')\n```\n \n## Development\n\nThe sommer package is under active development. If you are an expert in mixed models, statistics or programming and you know how to implement of the following:\n\n+ the minimum degree ordering algorithm \n+ the symbolic cholesky factorization\n+ automatic differentiation\n+ generalized linear models\n\nplease help us to take sommer to the next level. Drop me an email or push some changes through github :)  \n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcovaruber%2Fsommer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcovaruber%2Fsommer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcovaruber%2Fsommer/lists"}
