Predictive equations for bolted connections
… is hard to determine. Hence, statistical equations for predicting the eccentricity coefficients were developed by using the Buckingham's PI-Theorem and regression analysis. The precision of the statistical equations is discussed, and several ways to improve the precision are presented in …

Predictive equations for milk yield and dry matter intake and development of a maximum-profit ration formulation model
… and least square procedures were used to develop predictive modes for milk (R<sup>2</sup> = .807) and maximum dry matter intake (R<sup>2</sup> = .741). Season, days in lactation, fat percent, dry matter intake, body weight, and crude protein and concentrate percent of dry matter were identified as …

Analysis of riprap design methods using predictive equations for maximum and average velocities at the tips of transverse in-stream structures
… organized and arranged for regression analysis. Predictive equations were developed that describe the ratios of maximum and average velocity at the tips of the in-stream structures to bend-averaged velocities. The predictive equations for maximum and average velocity ratios function as a first …

Bioelectrical impedance analysis as a predictor of fish health and energy content in juvenile rainbow trout (Oncorhynchus mykiss)
… the fish. The focus of this study is to develop predictive equations non-lethally determine the water content, dry mass and energy content of juvenile rainbow trout (Oncorhynchus mykiss) and to determine whether the electrode position has an effect on the predictive capability of these equations. …

Prediction of performance time on a treadmill stress test following a Bruce protocol
… stepwise regression analysis was used to develop equations from the research parameters established on the questionnaire, and resulted in two useful predictive equations, one for males and one for females. Results indicated 52 males and 33 females had actual treadmill times of six minutes or …
