Generate a destructive-sampling developmental branching control — synthetic_branching

Generates independent samples at five observed developmental stages. Early samples occupy a shared trunk; after a declared branch point, samples enter one of two terminal states. The two-dimensional state geometry is embedded along two orthonormal feature directions in a single high-dimensional expression matrix. This is a disclosed visualisation and development control, not validation evidence for a two-dimensional dynamics estimator.

Usage

synthetic_branching_control(
  n_per_stage = 24L,
  p = 200L,
  noise_sd = 0.08,
  branch_point = 0.42,
  seed = 42L
)

Arguments

n_per_stage: integer number of independent samples per observed stage
p: integer number of expression features
noise_sd: numeric expression noise standard deviation
branch_point: numeric location of the planted divergence on scaled time
seed: integer RNG seed for reproducibility

Value

single-omic-layer StateTransitionData with planted two-axis SubspaceGroundTruth and branching metadata
