RDS

Compute a test of trend in prevalences based on a likelihood-ratio statistic

Compute a test of trend in prevalences based on a likelihood-ratio statistic

MA Estimates

This package provides functionality for carrying out estimation with data collected using Respondent-Driven Sampling. This includes Heckathorn's RDS-I and RDS-II estimators as well as Gile's Sequential Sampler estimator.

Homophily Configuration Graph Estimates

Compute RDS-I Estimates

RDS-II Estimates

Gile's SS Estimates

RDS Bootstrap Interval Estimates

Compares the rates of two variables against one another.

Compares the rates of two variables against one another.

converts to character with minimal loss of precision for numeric variables

Coerces a data.frame object into an rds.data.frame object.

Does various checks and throws errors if x is not a valid rds.data.frame

Performs a bootstrap test of independance between two categorical variables

Calculates incidence and bootstrap confidence intervals for immunoassay data collected with RDS

Bottleneck Plot

Compute estimates of the sampling weights of the respondent's observations based on various estimators

Auxiliary for Controlling RDS.bootstrap.intervals

Convergence Plots

Counts the number or recruiter->recruitee transitions between different levels of the grouping variable.

Calculates estimates at each successive wave of the sampling process

Differential Activity between groups

Convert the output of print.rds.interval.estimate from a character data.frame to a numeric matrix

A Simulated RDS Data Set

Get Horvitz-Thompson estimator assuming inclusion probability proportional to the inverse of network.var (i.e. degree).

Get the subject id

Returns the network size of each subject (i.e. their degree).

Calculates the number of (direct) recuits for each respondent.

Returns the population size associated with the data.

Returns the recruitment time for each subject

Get recruiter id

Calculates the root seed id for each node of the recruitement tree.

Gets the recruiter id associated with the seeds

Markov chain statistionary distribution

Calculates the depth of the recruitment tree (i.e. the recruitment wave) at each node.

Weights using Giles SS estimator

RDS data.frame has recruitment time information

homophily configuration graph weights

This function computes an estimate of the population homophily and the recruitment homophily based on a categorical variable.

Imputes missing degree values

Estimates each person's personal visibility based on their self-reported degree and the number of their (direct) recruits. It uses the time the person was recruited as a factor in determining the number of recruits they produce.
