Under current standards, the auditor is required to achieve a low level of risk of a type II error, but there is no similar prescription for a type I error. In the study, researchers developed an economic model based on the basic assumptions that even though auditors aim to please clients, they also strive to maintain the costs of an audit as planned and to comply with standards.

(2002), increased concurvity in the data used to fit a semiparametric spatial GAM leads directly to increased downward bias in the estimated standard error of the fitted linear parameter and, consequently, to inflated type I error in the standard significance test of this effect.

However, we also need to recognize that there are usually consequences to type I errors as well (i.e., the ripples).
