sim.chisq.test.gf {simitation}

sim.chisq.test.gf

Description

Perform a chi-squared test of goodness of fit across one or more experiments.

Usage

sim.chisq.test.gf(
  simdat.chisq.gf,
  hypothesized.probs = NULL,
  correct = TRUE,
  experiment.name = "experiment",
  value.name = "x"
)

Arguments

simdat.chisq.gf

Data for use in chi squared tests of goodness of fit across one or more experiments. The structure should be in the form returned by the function simitation::sim.chisq.gf().

hypothesized.probs

A vector of hypothesized probabilities corresponding to the values in the column specified by value.name. If the values include c("B", "A", "C"), then a probability vector of c(0.5, 0.3, 0.2) would associate a value of 0.5 with "A", 0.3 with "B", and 0.2 with "C".

correct

Logical. For details, refer to the chisq.test documentation.

experiment.name

A character value providing the name of the column identifying the experiment.

value.name

A character value providing the name of the column identifying the values.

Value

A data.table or data.frame with the results of the chi-squared tests.

Examples

simdat.chisq.gf <- sim.chisq.gf(n = 100, values = LETTERS[1:4], prob =
c(0.4, 0.3, 0.2, 0.1), num.experiments = 2,
experiment.name = "experiment_id", value.name = "classification", seed = 31)

test.statistics.chisq.test.gf <- sim.chisq.test.gf(simdat.chisq.gf =
simdat.chisq.gf, hypothesized.probs = c(0.25, 0.3, 0.15, 0.3),
correct = FALSE, experiment.name = "experiment_id", value.name =
"classification")
