### Random Coefficients Regression

RPD – Section 18.3

Basic Model
• Simple Linear Regression where each of n experimental units is observed at t points in time (typically)
General Model (Gumpertz and Pantula (1989))
• Possibly Multiple Linear Regression where each of n experimental units is observed at t points in time, based on regression with k parameters
Example – Annual Air Revenues for 10 Markets
• Random Sample of n = 10 large air markets (City Pairs), each observed over 5 years
• Y = ln(Average Fare * Average weekly Passengers)
• X = Year (1996/7=0, 2000/1=4) – Note: All Cities have same levels of X (not necessary for the method)
