vpredict: Form functions of variance components from an
||A two-sided formula, where the left-hand side labels the estimate. The right-hand side defines the derived parameter as an algebraic expression. Any of the estimated parameters can be included, represented as
The standard error of the computed value is calculated using the delta method using deriv(), which calculates algebraic derivatives for a wide range of expressions. The variance components are represented in the expression by “V1”, “V2”, “V3”, etc.
|A single-row data frame with components:|
|Estimate||The result of the algebraic expression.|
|SE||The estimated standard error.|
