A small collection of data on graduate statistics programs from the United States.

Implements confidence interval and sample size methods that are especially useful in psychological research. The methods can be applied in 1-group, 2-group, paired-samples, and multiple-group designs and to a variety of parameters including means, medians, proportions, slopes, standardized mean differences, standardized linear contrasts of means, plus several measures of correlation and association. The confidence intervals and sample size functions are applicable to single parameters as well as differences, ratios, and linear contrasts of parameters.  The sample size functions can be used to approximate the sample size needed to estimate a parameter or function of parameters with desired confidence interval precision or to perform a variety of hypothesis tests (directional two-sided, equivalence, superiority, noninferiority) with desired power.

Generates a random quotation from a database of quotes on topics
    in statistics, data visualization and science. Other functions allow searching
    the quotes database by key term tags, or authors or creating a word cloud.
    The output is designed to be suitable for use at the console, in Rmarkdown
    and LaTeX.

A set of methods to implement Generalized Method of Moments and Maximal
    Likelihood methods for Random Utility Models. These methods are meant to
    provide inference on rank comparison data. These methods accept full,
    partial, and pairwise rankings, and provides methods to break down full or
    partial rankings into their pairwise components. Please see Generalized
    Method-of-Moments for Rank Aggregation from NIPS 2013 for a description of
    some of our methods.

Tools to help download, process and analyse the UK road collision data collected using the
  'STATS19' form. The datasets are provided as 'CSV' files with detailed road safety information about the
  circumstances of car crashes and other incidents on the roads resulting in casualties in Great Britain
  from 1979 to present. Tables are available on 'colissions' with the circumstances (e.g. speed limit
  of road), information about  'vehicles' involved (e.g. type of vehicle), and 'casualties' (e.g. age).
  The statistics relate only to events on public roads that were reported
  to the police, and subsequently recorded, using the 'STATS19' collision reporting form. See
  the Department for Transport website 
  <https://www.data.gov.uk/dataset/cb7ae6f0-4be6-4935-9277-47e5ce24a11f/road-safety-data> for more
  information on these datasets.
  The package is described in a paper in the Journal of Open Source Software
  (Lovelace et al. 2019) <doi:10.21105/joss.01181>.

  methodological and empirical road safety research.
