Simulate Meta Variables
Description
This function simulates meta-variables with varying distributions to append to some data.
Usage
simulateMeta(
data,
outcome = colnames(data)[1],
metaInfo = data.frame(var = c("randUnif", "randBin", "rNorm", "corrUnif", "corrBin",
"corrNorm"), rdist = c("runif", "rbinom", "rnorm", "runif", "rbinom", "rnorm"),
outcome_0 = c("0.5", "0.5", "1", "0.5", "0.6", "1"), outcome_1 = c("0.5", "0.5", "1",
"0.75", "0.65", "1.5"), outcome_2 = c("0.5", "0.5", "1", "0.95", "0.75", "1.5"))
)
Arguments
data |
Data.frame with the outcome and unit. Typically this also includes PCA data as it is run after computing the principle components (see examples). |
outcome |
(Optional) String for column title of the data's outcome. Default is the first column. |
metaInfo |
(Optional) Data.frame indicating the meta-variables (and properties) to generate. Default has some examples of possible options. The data.frame has a var column, rdist column, and columns for each outcome. The var column names the meta-variables, rdist indicates the distribution (options are runif, rbinom, and rnorm), and the outcome columns indicate mean of the variable for that outcome. In order to allow designation of the expected values, the following rules are imposed on each distribution:

Details
Notes: runif may induce useless information so don't recommend correlating it
Value
Data.frame of the original data with meta-variables appended (as columns) at the end.
Examples
data <- simulatePP(
agentVarData = data.frame(
"outcome" = c(0, 1, 2),
"A" = c(0, 0, 0),
"B" = c(1 / 100, 1 / 500, 1 / 1000)
),
agentKappaData = data.frame(
"agent" = c("A", "B"),
"clusterAgent" = c(NA, "A"),
"kappa" = c(10, 3)
),
unitsPerOutcome = 5,
replicatesPerUnit = 1
)
pcaData <- getKsPCAData(
data = data, replicate = "replicate",
xRange = c(0, 1), yRange = c(0, 1)
)
pcaMeta <- simulateMeta(pcaData)
## Another simple example
data <- simulateMeta(
data.frame("outcome" = c(0, 0, 0, 1, 1, 1), "unit" = 1:6)
)
