The released version of scry can be found on Bioconductor at https://bioconductor.org/packages/scry.
A collection of methods for the analysis of small-count data, such as single-cell RNA-seq.
Included methods:
- Deviance for feature selection
- GLM-PCA for dimension reduction
- Null residuals, a transformation that when combined with PCA approximates GLM-PCA
Planned additions for upcoming release:
- Quasi-UMI normalization for single-cell read counts
- Cell type prediction for scRNA-seq
## Installation
