New month-to-month rates into 2nd web page of your G.19 are calculated off indication data using proportional interpolation. step 1 Proportional interpolation remedies another optimisation situation:
in which t = 0 ‘s the prior standard period and you may t = T is the most recent or upcoming benchmark period. Likewise, , and are the fresh new month-to-month guess and you can indication at big date t, respectively, in fact it is new standard from the time t. Proportional interpolation reduces the full total squared differences between this new proportion of the estimate toward indication inside every month and you may the one early in the day, susceptible to brand new restriction that guess equals new benchmark inside the each standard period.
