The current I , developed by Charles J. Neumann in the 1960s, i based on only 13 years of data taken over 30 years ago. The index was in desperate need of an upgrade.

After performing the multiple regressions and retuning the regression coefficients, both NPTs were validated using a 2-year independent …
