This
result holds up quite well in a number
of robustness checks, and we show that the predictive power
of the average IV might come from its close relation with systematic risk omitted from CAPM.
it is important to recognize that an inherent difficulty
of testing null hypotheses is that one can not confirm (statistically) the hypothesis
of no effect.While
robustness checks (reported in the appendix), as well as p values that never approach standard levels
of statistical significance, provide some confidence that the
results do not depend on model specification or overly strict requirements for statistical significance, one can not entirely dismiss the possibility
of a Type II error.
The convergent validity
of these models provides a
robustness check for our
results.

of results was largely replicated in
robustness checks using observed data, and the classes were associated with relevant socioeconomic factors in a meaningful way, increasing our confidence that the LCA has captured meaningful patterns in the income data.
