simitation (version 0.0.7)

sim.chisq.test.gf: 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"
)

Value

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

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.

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")
