Calculates the Chi-square approximation to the z-test and the binomial approximation to the z-test.

1 | ```
z_tests_cfa(observed, expected, ccor = FALSE, ntotal = sum(observed))
``` |

`observed` |
a vector giving the observed frequencies. |

`expected` |
a vector giving the expected frequencies. |

`ccor` |
either a logical (TRUE / FALSE) determining wether to apply a continuity correction or not. When set to |

`ntotal` |
optional a numeric giving the total number of observations. By default ntotal is calculated as |

An continuity correction can be applied to the binomial approximation – see argument `ccor`
