Hi,
I hope that someone can help me write the right commands.
I have a data set with 3 columns
player_name|number_goals|year|day
not every player is listed for every year-day-hour
I would like to compute the "growth rate" of each player A so if player
scored on day X 3 goals and on day X+1 6 goals then her grow rate is 100% ..
If she did not score on day X then maybe we set a default scoring value of 1
on day X .. I am looking for ways to deal with that.
Finally I have another data set with 2 columns
player_name|growth_rate|year|day , I would like to compute the average
growth rate from day X to X-1, from day X to X-2, from day X to X-3 .. etc
Does anyone know a package that will enable me to complete these tasks
easily?
Thank you for your time.
