View source: R/CalcNpmleCalibP.R

For a given time point, calculate the probability of positive exposure value for multiple observations (participants). The function uses the results of a nonparametric calibration model fit, and given collected data on the history of the binary exposure for each participant.

1 | ```
CalcNpmleCalibP(w, w.res, point, fit.npmle)
``` |

`w` |
A matrix of time points when measurements on the binary covariate were obtained. |

`w.res` |
A matrix of measurement results of the binary covariate. Each measurement corresponds to the time points in |

`point` |
The time point at which the probabilities are estimated. |

`fit.npmle` |
The result of |

A vector of estimated probabilities of positive exposure status at time `point`
