Month-on-Month PCE Deflator Inflation: Has the Regime Switched?

This yields the following program possibilities (filtered, smoothed):.

Heading CPI and PCE deflator month-on-month inflation looks like theyre down. So too for core CPI and PCE deflator. In order to make a more official evaluation, I approximate a simple Markov-switching design (2 regimes, various differences) over the 1960-2022 period.

Core PCE inflation was at agreement, 0.2% m/m. Are we in a new inflation routine?

As of November 2022, the possibility of being in the high inflation regime is 15%.
Since the decline in core inflation is less significant, the estimated possibility for being in the high inflation program is 80%
