Generating data with multiple index

General Usage
1 
J= 3  #numeber of agents
T = 24  # time horizon 
W= 100  #Numebr of scenario
d_jtw_mean = [50 ,70,90]
d_jtw_std = 0.25
d_jtw_sigma = d_jtw_std*d_jtw_mean
dd = MvNormal(d_jtw_mean, d_jtw_sigma)
d_jtw= rand(dd,W)
which gives me:
3×100 Array{Float64,2}:
  79.8875   56.4883  41.972   71.3829  …  55.0853  60.5764  46.6175  48.4329
  76.4444   76.8151  59.0371  71.5851     85.2243  59.146   34.0514  60.9782
 104.403   126.268   76.4281  49.1581     47.1082  80.8507  67.6481  79.5638
However, I expecte 3x24x100 as the data is indexed with [j,t,w];index with  with 3 dimension.
Anyone who can give me a hint todo that?
Thanks.

reshape(rand(dd,T*W),3,T,W)
