adedis | adedis computes estimates of the slope coefficients in a single index model. The coefficents of the continuous variables are estimated by (an average of) dwade (density-weighted average derivtive) estimates. The coefficients of the disrete explanatory variables are estimated by the method proposed in Horowitz and Haerdle, JASA 1996. |

select | select calculates semiparametric estimators of the intercept and slope coefficients in the "outcome" or "level" equation of a self-selection model. select is therefore the second stage of the two-stage procedure used to estimate these models. select does not estimate the coefficients of the "selection" or "decision" equation but requires that the estimated first-step "index" be given as an input. The procedure to estimate the slope coefficients is desribed in Powell (1987). The procedure to estimate the intercept coefficient is desribed in Andrews and Schafgans (1994). select combines the powell and andrews macros of the metrics library. |

sir | Calculates the effective dimension-reduction (edr) directions by Sliced Inverse Regression (Li, 1991) |
sir1 | This macro is the taylored Sliced Inverse Regression method for the "sssm" macro. Here, the macro "sir1" builds a special slice which contains the cases such that y=0 (the value "0" for y symbolically indicates a missing value). Then, nbslices (by default, nbslices=5) other slices are made by splitting the range of the non missing y's into slices of nearly equal weight (i.e. such that they contain nearly the same number of cases). The classical algorithm of S.I.R. is then used with this special slicing. |
sir2 | Calculates the effective dimension-reduction (edr) directions by Sliced Inverse Regression II (Li, 1991) |
sssm | computes the estimates of the slope vectors in the outcome equation and in the selection equation for a semiparametric sample selection model (SSSM). This is a two-stages estimation method: the first one is a taylored Sliced Inverse Regression (S.I.R.) analysis, and, in the second one, two Canonical analyses are conducted in order to convert the estimated EDR directions into estimates of the slopes. The identifiability conditions have to be verified: there exists a component of the explanatory variable X which affects the selection and does not affect the outcome, and there also exists another component of X which affects the outcome and does not affect the selection. If these identifiability conditions are not verified, the program stops. Moreover, the number of explanatory variables for the selection (resp. outcome) equation must be greater or equal than 2. |
