ψ=(D−m₀(Z))×(Y−g₀(Z)−(D−m₀(Z))θ), where the multiplying terms are the error terms of our partially linear model, although other alternatives are available. Now, we require this score function to be equal to zero, ψ=0, which constitutes our moment condition. This is mathematically expressing that we
