calcPolyInLBase function

Internal function for retrieving regression function coefficients at specific age

The function is an inline for searching zeros in the inverse regression function. It collapses the regression function at a specific age and simplifies the coefficients.

calcPolyInLBase(raw, age, coeff, k)

Arguments

• raw: The raw value (subtracted from the intercept)
• age: The age
• coeff: The cNORM regression model coefficients
• k: The cNORM regression model power parameter

Returns

The coefficients
