Correction of the significance level when attempting multiple transformations of an explanatory variable in generalized linear models

BACKGROUND In statistical modeling, finding the most favorable coding for an exploratory quantitative variable involves many tests. This process involves multiple testing problems and requires the correction of the significance level. METHODS For each coding, a test on the nullity of the coefficient associated with the new coded variable is computed. The selected coding corresponds to that as...
