will this cdata.pci_t = (cdata.pci_t - cdata.pci_t.mean()) / cdata.pci_t.std()
be correct for PCI calculation?
The "correct" values are the ones the package outputs (with the ECI mean / std used for normalization). You can also work with the unnormalized indices themselves - the normalization is just a statistical treatment on top that lets us get the nice property described in the books and the link I sent above.
Dear team,
I was wondering about the PCI calculation. You have a equation:
Shouldn't it be
cdata.pci_t = (cdata.pci_t - cdata.pci_t.mean()) / cdata.pci_t.std()
according to the https://growthlab.cid.harvard.edu/files/growthlab/files/atlas_2013_part1.pdf , page 24.?
