Compute the Evil Twins / Extreme EWMA cap for given intervals and weights. Vectorized: interval_months and uw can be vectors.

Source: R/adult_support.R
compute_et_limit.Rd

For built-in formulas (piecewise, piecewise-lower, allofus15), ET caps are derived from the formula's wtallow caps + 20 (for PW-H/PW-L) or equal to the allofus15 12m cap. For custom CSV formulas, fixed caps of 70/100 are used.

Usage

compute_et_limit(interval_months, formula = "piecewise", uw = NULL)

Arguments

interval_months

Interval in months (minimum neighbor gap)

formula

Character: "piecewise", "piecewise-lower", "allofus15", or path to custom CSV

uw

Optional numeric vector of upper weights (higher of two adjacent weights, or max(wt, ewma)). NULL = use base (UW=120) caps.

Value

Numeric vector of ET limits
