Hi:
I have usually used the GROWTH() excel function to do this but now want to see
if I can do this with R.
I want to predict values into the future, possibly with the predict.arima
Function.
I have the following weekly fish weight averages:
weight <- c("2.1","2.4","2.8","3.6","4.1","5.2","6.3")
week <- c("1","2","3","4","5","6","7")
I would like to predict what the weight will be by week 10 based on my weight
values and make a line plot of all the weights(including the predicted values).
I have two questions:
1- Should the predicted values be linear or exponential?
2- Is the predict.arima function appropriate to do this?
Thanks in advance.
