Generate a random normally distributed version of a weitrix

Values are generated with variance equal to 1/weight. This can be used to see what R-squared would be achieved with purely random data, and therefore an appropriate number of components to use. This is known as Parallel Analysis.

weitrix_randomize(weitrix)

Arguments

weitrix	A weitrix object, or an object that can be converted to a weitrix with as_weitrix.

Value
