I need to estimate the mean value in a network for each dimension of a 3-dimension variable (var_1
) . The code I've written doesn't quite do the trick:
set avg-network map mean ([var_1] of turtles)
What this does is calculating the average for all three dimensions of each turtle instead of the average for each dimension for all turtles. That is:
Turtle0 [0 0 0]
Turtle1 [1 1 1]
Turtle2 [2 2 2]
Turtle3 [3 3 3]
Gives [0 1 2 3]
instead of [2 2 2]
which is what I am after...
I found a way using the matrix
extension. What I do is:
extensions [ matrix ]
to-report temp-matrix
let m matrix:from-row-list ([var_1] of turtles)
report m
end
to go
let i 0
set avg-network n-values 3 [0]
repeat 3 [
set avg-network replace-item i avg-network (mean matrix:get-column temp-matrix i)
set i (i + 1)
]
end
Not the most elegant but it does the trick. If anyone knows another way I am happy to hear!
