chi2_test_BFF {BFF} | R Documentation |

## chi2_test_BFF

### Description

chi2_test_BFF constructs BFFs based on the t test. BFFs depend on hyperparameters r and tau^2 which determine the shape and scale of the prior distributions which define the alternative hypotheses. By setting r > 1, we use higher-order moments for replicated studies. Fractional moments are set with r > 1 and r not an integer. All results are on the log scale.

### Usage

```
chi2_test_BFF(
chi2_stat,
n,
LRT = FALSE,
omega = NULL,
omega_sequence = if (is.null(omega)) seq(0.01, 1, by = 0.01),
r = 1
)
```

### Arguments

`chi2_stat` |
chi-square statistic |

`n` |
sample size (if one sample test) |

`LRT` |
should LRT be performed? Default is FALSE |

`omega` |
standardized effect size. For the chi^2-test, this is often called Cohen's w (can be a single entry or a vector of values) |

`omega_sequence` |
sequence of standardized effect sizes. If no omega is provided, omega_sequence is set to be seq(0.01, 1, by = 0.01) |

`r` |
variable controlling dispersion of non-local priors. Default is 1. |

### Value

Returns an S3 object of class 'BFF' (see 'BFF.object' for details).

### Examples

```
chi2BFF = chi2_test_BFF(chi2_stat = 6.5, n = 10)
chi2BFF
plot(chi2BFF)
```
