Python object: phenotypic.schema._double_softplus_model.DOUBLE_SOFTPLUS_MODEL

Category: DoubleSoftplus

Column label	Description
DoubleSoftplus_v	The post-lag phase growth rate.
DoubleSoftplus_s0	The initial size
DoubleSoftplus_lambda	The duration of the lag phase
DoubleSoftplus_alpha	lag phase transition sharpness
DoubleSoftplus_smax	Carrying capacity used by the model. Either the user-provided scalar or the per-group observed maximum.
DoubleSoftplus_beta	Saturation transition sharpness. Fitted per-group when a saturation shoulder is detected and beta is None at construction; held at the user-provided scalar (or the module default) when no shoulder is present.
DoubleSoftplus_mode	Fit variant selected per-group: ‘fixed_beta’ (beta held at the user-provided or module-default value) or ‘fitted_beta’ (beta fitted as a 5th free parameter when a saturation shoulder is detected).
