⚠️There's a newer version (1.5.8) of this package.Take me there.

lqmm (version 1.5.5)

Linear Quantile Mixed Models

Description

Functions to fit quantile regression models for hierarchical data (2-level nested designs) as described in Geraci and Bottai (2014, Statistics and Computing) . A vignette is given in Geraci (2014, Journal of Statistical Software) and included in the package documents. The packages also provides functions to fit quantile models for independent data and for count responses.
