Quantlet: pantime
Description: Subtracts the mean of period t from the model variables. Purpose: Accounting for fixed time effects

Reference(s):

Usage: (y)=pantime(z,{T})
Input:
z Data matrix. First column: Identification number for cross section units (optional), Second column: depen- dent variable, Further columns: explanatory variables
T Number of time periods for a BALANCED Dataset. Optional, only for a Dataset with the same T for all Individuals = BALANCED PANEL
Output:
y Data matrix with deviations of the time mean

Note:

Example:

library("metrics")

z=read("earnings") 

y=pantime(z)

y
