unusual facts about Standard error

Heteroscedasticity

For example, if OLS is performed on a heteroscedactic data set, yielding biased standard error estimation, a researcher might fail to reject a null hypothesis at a given significance level, when that null hypothesis was actually uncharacteristic of the actual population (making a type II error).

Runtime error 200

Runtime error 200 is the standard error message by Borland's Pascal compilers, standing for Division by zero.

Wald test

The other reason is that the Wald test uses two approximations (that we know the standard error, and that the distribution is chi-squared), whereas the likelihood ratio test uses one approximation (that the distribution is chi-squared).
