Latent Variable Modelling
For a more technical treatment of some of the topics later in the module, I recommend “Latent Variable Models and Factor Analysis: A Unified Approach” Bartholomew, Knott, and Moustaki (2011), which is available online via the UCL library
Latent Dirichlet Analysis
Latent Dirichlet Analysis is a method for class mixture modelling, particularly useful for analysing word count data.

Correspondence Analysis
Correspondent analysis is, roughly speaking, principle components analysis for count data.

Multidimensional Scaling
Multidimensional scaling methods simplify a large number of distance measures into coordinates in a small number of dimensions, almost always 2. They provide a way to take multiple senses of distance and simplify them into something that looks like a map.
Confirmatory Factor Analysis and Structural Equation Modelling
Confirmatory factor analysis and structural equation modelling are tools for modelling relationships between observed and latent variables, and are a book-length topic in their own right. In principle, structural equation modelling allow one to integrate the task of measurement with descriptive/causal modelling, although in practice most applied structural equation modelling is quite naive with respect to the difficulty of making compelling causal claims.
