Linear extrapolation step of SIMEX algorithm.
1 | linearextrapolation(A1, A2, A3, lambda)
|
A1 |
estimates obtained from each level of labmda. |
A2 |
variances estimates obtained from each level of lambda. |
A3 |
scale estimates obtained from each level of lambda. |
lambda |
vector of lambdas, the grids for the extrapolation step. |
reg1 |
extrapolation back to lambda=-1 yield the SIMEX estimates |
reg2 |
extrapolation back to lambda=-1 yield the SIMEX estimates of variances |
scalereg |
extrapolation back to lambda=-1 yield the SIMEX estimates of scale |
