Your equation simplifies down to: . . . . .Y = a + c + d + bY . . . . .Y - bY = a + c + d . . . . .Y = (a + c + d) / (1 - b) In other words, Y would appear to be a constant, and Z would appear to be irrelevant. As such, X will also be a constant. Was this what you meant? Also, which intercept were you seeking? Thank you! Eliz.
