Posterior summaries of STAGE transition points (m50) — transition_point.stage

Returns posterior summaries of \(m_{50}\), the value of \(x\) where \(P(y=1 | x) = 0.5\). Under equal class priors, \(m_{50}\) is the direct sampling parameter of the STAGE model.

Usage

# S3 method for class 'stage_fit'
transition_point(object, population = NULL, ...)

Arguments

object: A stage_fit object as returned by fit_stage().
population: Optional population index (integer) or label (character). If NULL, return global and all populations.
...: Currently ignored. Included for method compatibility.

Value

A named list. Always contains global (posterior summary of the global m50). For J > 1 models, also contains pop1, pop2, etc. for each population-specific transition point. Each summary is a named numeric vector with mean, median, q2.5, q97.5.
