Dado que la variable dependiente es una variable cualitativa de tipo binaria (1/0), se utilizo un modelo Logit, estimando la regresion a traves del programa estadistico LIMDEP 8.
8) Specifically, we used the LIMDEP statistical package to simultaneously estimate equation [3a] (or [3b]) and the following selection equation:
Models with two, three and four classes were estimated using LIMDEP 9.
For estimating parameters of the above-mentioned model, the econometric software LIMDEP, version 9.
This procedure has been implemented for this study using LIMDEP software (Greene, 2002), that provides <<selectivity-free>> estimates of the production function-record keeping relationship.
LIMDEP claims that the program can estimate the conditional logit only when the number of observations is no more than 20 or 30 observations per group.
To account for heteroskedasticity and autocorrelated error terms, we used a fixed-effects intercept model offered in LIMDEP econometric software (Greene, 1995).
Siguiendo la recomendacion de Cameron and Trivedi's (1996), ambos modelos de regresion, Poisson y binomial negativo, fueron estimados mediante el software LIMDEP y realizamos un likelihood ratio test bajo la hipoesis nula de que el parametro de dispersion en el modelo binomial era igual a 0.

Thus, to adjust for sample attrition, we conducted longitudinal analysis of changes in ADL and IADL status between the four sample waves using Tobit regression, with the sample selection using LIMDEP 7.
