I have data panel. I try to calculate the average change in variable "cashratio"
1. Variable "SIC", consist of: construction, manufacturing and retail trade;
2. Variable "Year" : the time range is from 2004 to 2014;
Question:
1. How to calculate average change in cash ratios for all industries as a whole (SIC) and for each industry (construction, manufacturing and retail trade) over time (2004 to 2014)
would appreciate any help
many thanks
