Added Sunday Dec 13th, 2020What is this?
Description from site: Provides transfusion-related differential tests on Near-infrared spectroscopy (NIRS) time series with detection limit, which contains two testing statistics: Mean Area Under the Curve (MAUC) and slope statistic. This package applied a penalized spline method within imputation setting. Testing is conducted by a nested permutation approach within imputation. Refer to Guo et al (2018) doi:10.1177/0962280218786302 for further details.

Cool functions from package:
- MAUCtest: MAUC statistics based Analysis for NIRS time series. Estimate the Mean Area Under the Curve (MAUC) statistics and conduct a nonparametric test on the MAUC difference before transfusion and after transfusion. If detection limit occurs at 15.
- plotNIRS: This function visualizes the NIRS time series data and estimates the underlying smoothed trend of the NRIS based on a nonparametric regression approach.
- Slopetest: Estimate the slope statistics and conduct a nonparametric based test on the slope difference before transfuion and after trasfusion. If detection limit occurs at 15
