Answer 1

7- The threats to Internal Validity are: ---------------------------------, Functional form misspecification, Errors-in-variables bias, Missing data and sample selection bias & --------------------------------------.

ANS- The threats to Internal Validity are: measurement errors, Functional form misspecification, Errors-in-variables bias, Missing data and sample selection bias & simultaneous causality bias.

8- ------------------------------- is the statistical inferences about causal effects that are valid for the population being studied.

ANS- Internal validity (A statistical analysis is internally valid if the )is the statistical inferences about causal effects that are valid for the population being studied.

9- Another term for panel data is -----------------------------------, n   ----------------------------------- & T being number of time periods.

ANS:Another term for panel data is longitudinal data, n being number of units & T being number of time periods.

10- The fixed effect regression methods for estimation produce identical estimates of the regression coefficients, and -------------------------------------------------.

ANS:The fixed effect regression methods for estimation produce identical estimates of the regression coefficients, and an estimate of a variable’s average effect within units over time
