Normal random number

Supported in: Batch, Streaming

Returns a column of normally distributed random numbers with zero mean and unit variance. This is not deterministic and will not produce the same result on repeated builds, even when using a seed.

Expression categories: Numeric

Declared arguments

  • optional Seed - Adding a seed means that the random numbers will be generated from same sequence at each build. If you want true random numbers this should not be supplied. A seed will not produce fully deterministic results since compute may run distributed and the order in which random numbers are pulled for rows is not guaranteed.
