Cramér-Wold theorem

Away from the thesis Wold and Cramér did some joint work, their best known result being the Cramér-Wold theorem (1936).

In mathematics, the Cramér-Wold theorem in measure theory states that a Borel probability measure on is uniquely determined by the totality of its one-dimensional projections.

In mathematical statistics, Wold contributed the Cramér-Wold theorem characterizing the normal distribution and developed the Wold decomposition in time series analysis.
