SE of the $h^2$ estimate (SE$\left\{h^2\right\}$) for $\left(Y_2=2\right)$ (tracking both sides of the parentage): (A) centered two-sided truncation, (B) right-sided truncation. To calculate actual SE$\left\{h^2\right\},$ values on the y-axis should be multiplied by factor $1/\sqrt{n},$ i.e., scaled by the experimental sample size.
