Interpret the estimated regression parameters
WebThe relationship between COPD severity, based on forced expiratory volume in 1 second (FEV 1 ), and different lung function parameters was analyzed by flexible nonparametric method, linear regression, and segmented linear regression with break-points. Results: Most lung function parameters were nonlinear in relation to spirometric severity. Webp are called the regression parameters. They are unknown and we will estimate them as part of the regression process. The g 0 (x i),...,g p (x i) are called the basis functions. …
