Score_test_1x2 {contingencytables} | R Documentation |

## The score test for the binomial probability (pi)

### Description

The score test for the binomial probability (pi) H_0: pi = pi0 vs H_A: pi ~= pi0 (two-sided) Described in Chapter 2 "The 1x2 Table and the Binomial Distribution"

### Usage

```
Score_test_1x2(X, n, pi0)
```

### Arguments

`X` |
the number of successes |

`n` |
the total number of observations |

`pi0` |
a given probability |

### Value

An object of the contingencytables_result class,
basically a subclass of `base::list()`

. Use the `utils::str()`

function
to see the specific elements returned.

### Examples

```
# The number of 1st order male births (Singh et al. 2010, adapted)
Score_test_1x2(singh_2010["1st", "X"], singh_2010["1st", "n"], pi0 = .5)
# The number of 2nd order male births (Singh et al. 2010, adapted)
Score_test_1x2(singh_2010["2nd", "X"], singh_2010["2nd", "n"], pi0 = .5)
# The number of 3rd order male births (Singh et al. 2010, adapted)
Score_test_1x2(singh_2010["3rd", "X"], singh_2010["3rd", "n"], pi0 = .5)
# The number of 4th order male births (Singh et al. 2010, adapted)
Score_test_1x2(singh_2010["4th", "X"], singh_2010["4th", "n"], pi0 = .5)
# Ligarden et al. (2010, adapted)
Score_test_1x2(ligarden_2010["X"], ligarden_2010["n"], pi0 = .5)
```
