The Toliman TSLs
also scored high in two other critical categories: field dispersal, or ability to roam throughout fields instead of staying in one place, and field survival, or ability to adapt to climate and other environmental conditions.
Table 3 reports the results of TSLS
estimation of the Senate election model.
estimation procedure is easiest to explain in a differences-in-differences framework.
Como visto anteriormente, porem, em casos em que a estimacao da regressao seja feita por TSLS
, nao e necessario incluir o termo de correcao de erro, ainda que as series sejam co-integradas.
Table 4 shows the results from TSLS
estimation of the effect of suicidal behaviors on the outcome variable for our preferred specification.
This effect is in the same range as the marginal effects of Medicaid coverage before pregnancy estimated from the OLS and single equation logistic models; the TSLS
estimate is positive but larger and insignificant.
To obtain correct standard errors (and t-statistics) a TSLS
regression was run (Column 4).
1995) attempts to circumvent the simultaneity problem by using two-stage least squares (TSLS
) or some related statistical procedure.
Both OLS and TSLS
were used to estimate these models.
We calculate a first-stage F-statistic for the joint insignificance of these two instruments and compare it using Stock and Yogo (2005)'s critical weak instrument test based on TSLS
size (see their Table 2).

and even two-stage least squares (TSLS
) yielded similar results.
