spreg.dgp.make_wxg

spreg.dgp.make_wxg(wx, gamma)

make_wxg: generate a column wxg as matrix wx (no constant)

times list gamma (coefficient of spatially lagged x)

Examples

>>> import numpy as np
>>> import libpysal
>>> from spreg import make_x, make_wx, make_wxg
>>> rng = np.random.default_rng(12345)
>>> x = make_x(rng,25,mu=[0],varu=[1])
>>> w  = libpysal.weights.lat2W(5, 5)
>>> w.transform = "r"
>>> wx = make_wx(x,w)
>>> print(wx.shape)
(25, 1)
>>> make_wxg(wx,[2,4])[0:5,:]
