WebAug 16, 2024 · The feature that distinguishes this approach from others such as ploynomials, splines or gams (to name a few) is that the parameters of the model have biologically meaningful interpretations. In R the approach that makes fitting nonlinear mixed models almost as easy as fitting linear mixed models is the use of self starting functions. WebWhen you do linear regression on only a constant, you will only get the intercept value, which is really just the mean of the outcome. In R we have: y <- rnorm (1000) lm (y ~ 1) # intercept = 0.00965 mean (y) # Equal to 0.00965 The reason for doing it the regression way, rather than just computing the mean, is to get an easy standard error. ear wax syringing at home
