Chapter 33 Mammary gland dataset

33.1 Introduction

This performs an analysis of the Bach et al. (2017) 10X Genomics dataset, from which we will consider a single sample of epithelial cells from the mouse mammary gland during gestation.

33.2 Analysis code

33.2.5 Variance modelling

We use a Poisson-based technical trend to capture more genuine biological variation in the biological component.

33.2.7 Clustering

We use a higher k to obtain coarser clusters (for use in doubletCluster() later).
