M. E. Greene, O. Rolfson, G. Garellick, M. Gordon, S. Nemes, Improved statistical analysis of pre- and post-treatment patient-reported outcome measures (PROMs): the applicability of piecewise linear ...

This paper develops some efficient algorithms for linear spline and piecewise multiple linear regression. A plotting procedure that shows the existence and location of changes in linear regression ...

S-shaped piecewise linear regression models were fitted with GH dose as the predictor variable and the Δ-value of the metabolic variables as response variables.

Subjects with previous SARS-CoV-2 infection are depicted in closed circles. The thick lines represent the mean estimate from the piecewise linear regression model using the estimated parameters.

The particular method we used for fitting growth curves was a piecewise linear regression model. The change in functional quotient was modeled as a linear function over short intervals of time. For ...
