smooth_erf function

Smooth exposure response function

Smooths exposure response function based on bandwidth

smooth_erf(matched_Y, bw, matched_w, matched_cw, x_eval, kernel_appr)

Arguments

• matched_Y: A vector of the outcome variable in the matched set.

• bw: The bandwidth value.

• matched_w: A vector of continuous exposure variable in the matched set.

• matched_cw: A vector of counter or weight variable in the matched set.

• kernel_appr: Internal kernel approach. Available options are locpol

  and kernsmooth.

Returns

Smoothed value of ERF
