# glimix-core
[](https://glimix-core.readthedocs.io/en/latest/?badge=latest)
Fast inference over mean and covariance parameters for Generalised Linear Mixed
Models.
It implements the mathematical tricks of
[FaST-LMM](https://github.com/MicrosoftGenomics/FaST-LMM) for the special case
of Linear Mixed Models with a linear covariance matrix and provides an
interface to perform inference over millions of covariates in seconds.
The Generalised Linear Mixed Model inference is implemented via Expectation
Propagation and also makes use of several mathematical tricks to handle large
data sets with thousands of samples and millions of covariates.
## Install
Via [pip](https://pypi.python.org/pypi/pip):
```bash
pip install glimix-core
```
## Usage
Here it is a very simple example to get you started:
```python
>>> from numpy import array, ones
>>> from numpy_sugar.linalg import economic_qs_linear
>>> from glimix_core.lmm import LMM
>>>
>>> X = array([[1, 2], [3, -1], [1.1, 0.5], [0.5, -0.4]], float)
>>> QS = economic_qs_linear(X, False)
>>> X = ones((4, 1))
>>> y = array([-1, 2, 0.3, 0.5])
>>> lmm = LMM(y, X, QS)
>>> lmm.fit(verbose=False)
>>> lmm.lml()

```
We also provide an extensive [documentation](http://glimix-core.readthedocs.org/) about the library.
