r scripts for qqt analysis

QQT

Replications files for the paper Quantity versus Quality: Household structure, number of siblings, and educational attainment in the long nineteenth century.

Data files

The data are harmonised in the qqtdata.r script. Most raw datafiles are available online:

• North Atlantic Population Project.
• Mosaic project.
• Canadian Families.
• National Archives of Ireland.

Change the working directory to match the location of the files. The harmonised files are left in a subdirectory called cleandata. A table of overall summary statistics is created as well.

Analyses

After processing the data, the analyses can be carried out in the qqtanalyses.r script. It first creates a number of plots, tables with summary statistics, and harmonised regressions, followed by all the regressions for the appendix.

Helper functions

The script qqtheader.r contains a number of functions used in the other two scripts.
