WebApr 14, 2024 · Self-lock compression anti-rotation blade (SCAB) is a novel internal fixation implant for femoral neck fractures (FNF). We conducted this finite element analysis study to evaluate the biomechanical performances of SCAB combined with a cannulated screw for fixation of Pauwels type III FNF. Three finite element models of Pauwels type III FNF … Structured distributed lag models come in two types: finite and infinite. Infinite distributed lags allow the value of the independent variable at a particular time to influence the dependent variable infinitely far into the future, or to put it another way, they allow the current value of the dependent variable to be … See more In statistics and econometrics, a distributed lag model is a model for time series data in which a regression equation is used to predict current values of a dependent variable based on both the current values of an See more Distributed lag models were introduced into health-related studies in 2002 by Zanobetti and Schwartz. The Bayesian version of the … See more The simplest way to estimate parameters associated with distributed lags is by ordinary least squares, assuming a fixed maximum lag $${\displaystyle p}$$, assuming independently and identically distributed errors, and imposing no structure on the … See more ARMAX Mixed data sampling See more
