6.7.11.6.1.1.3. statsmodels.sandbox.regression.treewalkerclass.RU2NMNL.get_probs

RU2NMNL.get_probs(params)

obtain the probability array given an array of parameters

This is the function that can be called by loglike or other methods that need the probabilities as function of the params.

Parameters:

params : 1d array, (nparams,)

coefficients and tau that parameterize the model. The required length can be obtained by nparams. (and will depend on the number of degenerate leaves - not yet)

Returns:

probs : array, (nobs, nchoices)

probabilites for all choices for each observation. The order is available by attribute leaves. See note in docstring of class
