| Description: | indirect average derivative estimation using binning |
| Usage: | {delta,dvar} = adeind(x,y,d,m) | |
| Input: | ||
| x | n x p matrix , the observed explanatory variable | |
| y | n x 1 matrix , the observed response variable | |
| d | p x 1 vector or scalar , the binwidth or the grid | |
| m | p x 1 vector or scalar , the bandwidth to be used during estimation of the scores | |
| Output: | ||
| delta | p x 1 vector , the ADE estimate | |
| dvar | p x p matrix , the estimated asymptotic covariance matrix of delta | |
