Usage

tma_fit_poly_curve(
  pts,
  x_col = NULL,
  y_col = NULL,
  time_col = "RowID",
  degree = NULL,
  max_degree = 3L,
  criterion = c("loocv", "aic"),

degree: Fixed polynomial degree (optional)
max_degree: Maximum degree to evaluate for LOOCV-2D (default 3)
criterion: "loocv" or "aic"
fit_curve_with_zero_pts: Logical; whether to retain (0,0) points
zero_eps: Tolerance for detecting (0,0) points

Value

List with fitted curve parameters, prediction closures, and metadata
