The free app allows users to save to realise their goals and allows them to virtually link their savings and current account to their Didid profile.
However, the differences-in-differences-indifferences (DIDID) estimate of this reduction was not significant at p<.
Table 3 shows the adjusted CABG rates before and after the implementation of the PHOJD, the pre--post differences in CABG rates, DID estimates ([PHQID Post--PHQID Pre]--[Non-PHQID Post-Non-PHQID Pre]), and DIDID estimates (DID Nonwhite - DID White) derived from the individual-level linear probability model (equation [2]) for patients diagnosed with AMI.
Sensitivity analysis that replaces the receipt of PTCA for the receipt of CABG as the dependent variable indicates that, although adjusted PTCA rates increased markedly from the pre- to the postperiod for each racial and ethnic cohort in both PHQID and non-PHQID hospitals, no DID and DIDID estimates were significant (see Appendix SA4).
study employed a similar DIDID estimation strategy (examining whether minority patients experienced a decrease in CABG rates, relative to whites, in New York (which had the public reporting program) relative to comparison states, before and after the public reporting program began).
Second, the DIDID estimates in the CABG analysis are somewhat imprecise, making inference uncertain and potentially subject to Type II error.
