Enum Vce 

pub enum Vce {
    Nn,
    Hc0,
    Hc1,
    Hc2,
    Hc3,
    Cr1,
    Cr2,
    Cr3,
}

Variance estimator, as rdrobust’s vce. As in rdrobust, the cluster-robust estimators need cluster labels and the others are switched to them when labels are given: Nn, Hc0 and Hc1 to Cr1, Hc2 to Cr2 and Hc3 to Cr3; without labels Cr1, Cr2 and Cr3 fall back to Hc1, Hc2 and Hc3.

Variants

Nn

Nearest-neighbour residuals (with at least nnmatch neighbours).

Hc0

Hc1

Hc2

Hc3

Cr1

Cluster-robust with the degrees-of-freedom correction.

Cr2

Bell and McCaffrey (2002) bias-reduced cluster-robust (CRV2).

Cr3

Pustejovsky and Tipton (2018) cluster-robust (CRV3).
