This function generates the TOST intervals for the intercept and the slope of the regression of y on x, and determines the smallest region of indifference in each case that would reject the null hypothesis of dissimilarity.

1 | ```
equiv.p(x, y, alpha = 0.05)
``` |

`x` |
The predictor variable - perhaps the model predictions |

`y` |
The response variable - perhaps the observations |

`alpha` |
The size of the test |

The generated confidence intervals are corrected for experiment-level size of alpha using Bonferroni.

A list of two items:

`Intercept` |
The smallest half-length of the interval that leads to rejection of the null hypothesis of dissimilarity for the intercept, in the units of y. |

`Slope` |
The smallest half-length of the interval that leads to rejection of the null hypothesis of dissimilarity for the slope, in the units of the slope. |

The accuracy of the output of this function is contingent on the usual regression assumptions, which are not checked here. Caveat emptor!
