What types of data generally exist?

Lösung anzeigen
TESTE DEIN WISSEN

1. Cross-sectional

2. Panel data

3. Time-series

TESTE DEIN WISSEN

What is the definition of panel data?

Lösung anzeigen
TESTE DEIN WISSEN

A panel dataset contains observations on multiple entities (individuals, states, companies. . . ), where each entity is observed at two or more points in time. Hypothetical examples:

  • Data on 420 California school districts in 1999 and again in 2000, for 840 observations total.
  • Data on 50 U.S. states, each state is observed in 3 years, for a total of 150 observations. 
  • Data on 1000 individuals, in four dierent months, for 4000 observations total.

For what do we need to calculate the t-statistic or the t-ratio?

Lösung anzeigen
TESTE DEIN WISSEN

If we want to test whether a mean of a variable Y (i.e., Y) with n observations is equal to a certain value (νY,0),

  • we can pool random cross sections and treat similar to a
    normal cross section. New dimension: time dierences.
  • we can follow the same random individual observations over
    time known as panel data or longitudinal data
