Factors influencing phosphorus losses in agroecosystems dominated by tile drainage
… mean concentrations. Along depression gradients, piecewise regression displayed a threshold at a depression depth of 0.38 m at which soil test phosphorus increased, indicating soil phosphorus accumulation at the bottom of closed depressions. Then, I evaluated how hydrologic drivers (precipitation, …

COMING OF AGE: A TALE OF TWO MATURITIES
… approaches, including analysis of variance, regression, and piecewise regression to better understand how these analyses shape our conclusions regarding the age of maturity of cognitive capacity and self-regulatory capacity. Age patterns found in the U.S. were consistent with past research. …

A Comparison of the Prediction Models for the Impact of Heat Wave on Total Mortality and Incidence of Heat-related Illness in the Republic of Korea
… of heat-related illness in Korea. Using piecewise regression model, the study was selected the best goodness of fit with the model which were calculated by adjusted R2 between mortality during the summer (1 June to 31 August) from 2001 to 2011 and incidence of heat-related illness during …

Development of a quantile-based approach to statistically downscale global climate models
… developed here, which is based on quantile regression, can downscale any variable simulated by AOGCMs and observed on a daily basis that has, or can be transformed into, a Gaussian-like or symmetrical distribution. One of the aspects of the quantile regression technique, along with our …

Dissolved organic matter dynamics in diverse freshwater ecosystems across Canada: long-term trends, transformations, and explanatory factors
… shifts in DOC patterns using LOESS smoothing and piecewise regression. I observed a stabilizing pattern or even a decrease in high acidification regions (Dorset and Nova Scotia), where increases in DOC were previously documented. At the low acid deposition region, IISD-Experimental Lakes Area, an …
