setPoissWeights(lam, wShape)

Poissionian weights.
pemtk.fit._stats.setPoissWeights(lam, wShape)[source]

Poissionian weights.

Set using https://numpy.org/devdocs/reference/random/generated/numpy.random.Generator.poisson.html

Pass (lambda, shape)

If int or float, set weights = rng.poisson(weights, data.shape). Note this operates per data-point, not per dimension.

  • If Xarray or np.array, use directly - must match size of data along key dimension, e.g. passing weights = rng.poisson(weights, data.t.size) will generate a distribution along the t-dimension.
