View source: R/threshold_slope.R

Finds the approximate value of `x (=x_th)`

for which the value of the psychometric function is equal thresh and the approximate value of slope in `x_th`

1 | ```
threshold_slope( pfit, xfit, thresh = 0.5 )
``` |

`pfit` |
estimated values of the psychometric function |

`xfit` |
stimulus levels in which the function was estimated |

`thresh` |
value for which to estimate threshold; default is 0.5 |

`value` |
Object with 2 elements: x_th: estimated threshold slope: estimated value of slope, i.e. derivative of pfit at x_th |
