Title: “Estimation and nonparametric inference for multilevel trends in river temperature, under haphazard sampling”

Speaker:
Dr. Slava Lyubchich, UMCES Chesapeake Biological Laboratory

Abstract:
Environmental scientists face multiple challenges when analyzing unevenly recorded time series with small sample sizes. For example, trends in water temperature may be confounded with time and date of sampling when the latter represent convenience samples, and thus introduce bias into regression estimates. We address these concerns using multilevel random slope models and nonparametric bootstrap inference for assessing the statistical significance of the annual trend in river temperature when measurement times and dates are haphazard.
