groupIndexes
to estimate group indexes using a group variable.yearOverYearIndexes
to estimate year-over-year indexes.predictedShareDissimilarity
to estimate the predicted share relative price dissimilarity measure. This has also been incorporated into priceIndex
to allow estimation of indexes using similarity linking and the new measure. imputeCarryPrices
to fill in missing observations using carry forward and carry backward prices.solveMethod
to GKIndex
now allows the GK equations to be solved by the iterative method. The matrix inverse method remains the default.priceIndex
now allows estimation of elementary indexes on a dataset that does not contain quantities. Previously a quantity variable was always required, but elementary indexes do not need it (in fact it may not exist).basePeriod
parameter of priceIndex
