It's just about how are you measuring the slope? Like, when you first learn derivatives and the math teacher draws a line between two points on a curve, then draws another from points closer together, then draws the tangent, then goes through how you get to a derivative function etc.
The yoy is just using two points very far apart. The mom is using two points closer together. It would be nice but practically impossible to measure it instantaneously, mom is about as good as we get.
I can get the prices for goods online, and then get them delivered to my house. Getting the CPI more often seems entirely feasible to me if we really wanted to.
Maybe. But online isn't the only place to buy, and to arrive at a single number they do all kinds of adjustments to account for seasons, locations etc.
If you are right, I'd guess the cost benefit probably isn't there regardless.
Which is still stupid to even be arguing about. It’s like people are trying to find a problem with data that is objectively reported by arguing that if you change the x axis you get an entirely different conclusion. No shit… that’s how data works.
No one is suggesting there is a problem with the data. They are discussing how best to interpret it.
And nobody is suggesting changing the x-axis. It's still time. The distinction people are making is which points does one use to calculate the slope? The most recent two? The most recent one and the one from a year ago? What are the implications of each?
From what I can gather you’re trying to suggest that prices are going down because “recently” they have been (which isn't even true MoM they’ve still increased). That’s a pretty sloppy and inaccurate statement without a very precise definition of recently, which has been omitted. And YoY it’s not true.
I didn't see any thread of discussion that you’re alluding to where people were trying to interpret what the data actually means. There was simply a word of caution about making sure not to let the headline confuse you. Then some incorrect and sloppy comments appeared like “actually this is incorrect data because the price is trending down MoM don’t be fooled”. That’s an entirely different thing. Hence why you see all the people trying to explain how it’s silly. I didn't introduce confusion by changing the slope calculation… I’m just responding to it trying to clean up the mess it’s made.
I’m seriously confused: what is your actual point?
