This class stores coefficients to scale KPI, first by geo and then
by mean and standard deviation of KPI.
A tensor of dimension (n_geos, n_times)
containing the KPI data,
used to compute the mean and stddev.
A tensor of dimension (n_geos,)
containing the population of
each geo, used to to compute the population scale factors.
