astroML.density_estimation.FunctionDistribution(func, xmin, xmax, Nx=1000, random_state=None, func_args=None)[source]¶ Generate random variables distributed according to an arbitrary function
- Parameters
- funcfunction
func should take an array of x values, and return an array proportional to the probability density at each value
- xminfloat
minimum value of interest
- xmaxfloat
maximum value of interest
- Nxint (optional)
number of samples to draw. Default is 1000
- random_stateNone, int, or np.random.RandomState instance
random seed or random number generator
- func_argsdictionary (optional)
additional keyword arguments to be passed to func
Methods
rvs(shape)Draw random variables from the distribution
