Visualize how degrees of freedom affect the shape of t distribution, visualize quantiles out of given probability and probability from a given quantile.

dist_t_plot(df = 3) dist_t_perc(probs = 0.95, df = 4, type = c("lower", "upper", "both")) dist_t_prob(perc, df, type = c("lower", "upper", "interval", "both"))

df | Degrees of freedom. |
---|---|

probs | Probability value. |

type | Lower tail, upper tail, interval or both. |

perc | Quantile value. |

Percentile for the `probs`

based on `df`

and
`type`

or probability value for the `perc`

based on `df`

and
`type`

.

`t_plot()`

, `t_prob()`

and `t_per()`

have been deprecated.
Instead use `dist_t_plot()`

, `dist_t_prob()`

and
`dist_t_perc()`

.
