Items are characterized by a set of attributes ( T ) and a collection of covariates (X) associated with those attributes. We wish to screen for acceptable items ( T E C T ) , but T is expensive to measure. We envisage a two-stage screen in which observation of X is used as a filter at the first stag
## Abstract Optimization of inversionβrecovery (IR) measurements of __T__~__1__~ relaxation times has focused on the efficiency of __T__~__1__~ estimation (precision per unit time), without explicit consideration of the total experimental time. With the modified fast IR method, the repetition time
