In jmeydam/countcheck: Detecting Count Anomalies Using Bayesian Hierarchical Models

Initialize data frame

Description

Constructs data frame with these fields:

• unit: ID for unit

• n: previous reference count values (measure of exposure), must at least be 1

• y: previous count values of interest

• n_new: new reference count values (measure of exposure), must at least be 1

• y_new: new count values of interest

• true_theta: true value of theta (if known)

• theta_nopool: no-pooling estimate of theta

• theta_complpool: complete-pooling estimate of theta

• theta_partpool: partial-pooling estimate of theta

• ucl_true_theta: UCL based on n_new and true value of theta (if known)

• ucl_nopool: UCL based on n_new and no-pooling estimate of theta

• ucl_complpool: UCL based on n_new and complete-pooling estimate of theta

• ucl_partpool: UCL based on n_new and partial-pooling estimate of theta

• fe_true_theta: factor f, with observed y_new exceeding true-theta UCL by f * sd(y_new), given n_new and true value of theta (if known)

• fe_nopool: factor f, with observed y_new exceeding no-pooling UCL by f * sd(y_new), given n_new and no-pooling estimate of theta

• fe_complpool: factor f, with observed y_new exceeding complete-pooling UCL by f * sd(y_new), given n_new and complete-pooling estimate of theta

• fe_partpool: factor f, with observed y_new exceeding partial-pooling UCL by f * sd(y_new), given n_new and partial-pooling estimate of theta

Vectors must be of equal length, with length >= 3. unit, n, y, n_new, y_new, and true_theta (if known) are initialized using the corresponding parameters. The other fields (and true_theta, if not known) are initialized with NA.

Usage

initialize(unit, n, y, n_new, y_new, true_theta = NULL)

n	Previous reference count values (measure of exposure), must at least be 1
y	Previous count values of interest
n_new	New reference count values (measure of exposure), must at least be 1
y_new	New count values of interest
true_theta	True value of theta (if known; optional)

Value
