%>% The magrittr pipe
addPriorGroups Add a column to tidy dataframe of draws that groups parameters by their prior distribution. All parameters with the same prior distribution recieve the same index.
baseballData Dataframe of 12,145 observations of baseball games in 2010
beachLocDF Dataframe where each row represents data about one of the 26 mile markers (fake) from mile 0 to mile 2.5 along the Ocean City, MD beach/boardwalk.
carModelDF Dataframe of 1000 (fake) observations of whether certain car buyers were willing to get information on a credit card speciailizing in rewards for adventure travellers.
chimpanzeesDF Data from behavior trials in a captive group of chimpanzees, housed in Lousiana. From Silk et al. 2005. Nature 437:1357-1359 and further popularized in McElreath, Richard. Statistical rethinking: A Bayesian course with examples in R and Stan. CRC press, 2020. Experiment
corruptDF Dataframe of 174 observations where information on the human developmet index (HDI) and the corruption perceptions index (CPI) both exist. Each observation is a country.
dagp_plot Plot posterior distribution of latent parameters in 'causact_graph' model.
dag_create Create a graph object focused on drawing a DAG.
dag_diagrammer The graph object should be of class 'causact_graph' and created using 'dag_create()'.
dag_dim Add dimension information to 'causact_graph'
dag_edge Add an edge (or edges) between nodes in a graph object.
dag_greta Generate a representive sample of the posterior distribution
dag_merge Merge two non-intersect 'causact_graph' objects
dag_node Add a node to an existing 'causact_graph' object
dag_plate Create a plate representation for repeated nodes.
dag_render Render the graph as an htmlwidget
delivDF 117,790 line items associated with 23,339 shipments.
generate_dot2 Generate DOT code using a graph object
grViz2 R + viz.js
gymDF Dataframe of 44 observations of free crossfit classes data Each observation indicates how many students that participated in the free month of crossfit signed up for the monthly membership afterwards
houseDF Dataframe of 1,460 observations of home sales in Ames, Iowa. Known as The Ames Housing dataset, it was compiled by Dean De Cock for use in data science education. Each observation is a home sale. See 'houseDFDescr' for more info.
houseDFDescr Dataframe of 523 descriptions of data values from "The Ames Housing dataset", compiled by Dean De Cock for use in data science education. Each observation is a possible value from a varaible in the 'houseDF' dataset.
meaningfulLabels Store meaningful parameter labels prior to running 'dag_greta()' of 'greta::mcmc()'. When 'greta' creates posterior distributions for multi-dimensional parameters, it creates an often meaningless number system for the parameter (e.g. beta[1,1], beta[2,1], etc.). Since parameter dimensionality is often determined by a 'factor', this function creates labels from the factors unqiue values. 'replaceLabels()' applies the text labels stored using this function to the 'greta' output. The meaningful parameter names are stored in an environment, 'cacheEnv'.
prodLineDF Product line and product category assignments for 12,026 partID's.
rbern Make dbern,pbern,qbern,rbern available for implementation of the Bernoulli distribution functions.
replaceLabels Replace parameter labels in a 'mcmc.list' with more meaningful labels after they are created by running 'dag_greta()'. When 'greta' creates posterior distributions for multi-dimensional parameters, it creates an often meaningless number system for the parameter (e.g. beta[1,1], beta[2,1], etc.). Since parameter dimensionality is often determined by a 'factor', this functionality restores the text labels associated with the underlying factor whose coefficients are being estimated (e.g. beta_varValue1, beta_varValue2). The meaningful parameter names are stored in an environment, 'cacheEnv', created by a call to 'dag_greta()'.
replace_in_spec2 Razor-like template for diagram specification
schoolsDF This example, often referred to as 8-schools, was popularized by its inclusion in Bayesian Data Analysis (Gelman, Carlin, & Rubin 1997).
setDirectedGraphTheme Set DiagrammeR defaults for graphical models
ticketsDF Dataframe of 55,167 observations of the number of tickets written by NYC precincts each day Data modified from https://github.com/stan-dev/stancon_talks/tree/master/2018/Contributed-Talks/01_auerbach which originally sourced data from https://opendata.cityofnewyork.us/
totalBeachgoersRepSample A representative sample from a random variable that represents the annual number of beach goers to Ocean City, MD beaches on hot days. Think of this representative sample as coming from either a prior or posterior distribution. An example using this sample is can be found in The Business Analyst's Guide To Business Analytics at https://www.causact.com/.
