You're just waffling and hurling abuse now Roddy. You simply don't know what you're talking about.
Here are a few of your silly blunders...
1. You claimed there were only four components (there are five) 2. You said Z can't be calculated for a ratio (it can, and is, by respected international organisations) 3. You claimed Z for the average can be -0.5 (Z for the average is always zero) 4. You suggested a z-score is not a deviation from an average (that's exactly what it is)
These are total rookie errors. You have no idea how to use z-scores. You don't really even understand what a z-score is.
Please just go away and read a comic or something.

So a z-score for a bubble meter comprised of components or chi-square distribution can only be 0? Nice one.
Better get you in front of Citi in the creepy crown suit to tell them what they're doing wrong. I would give it a good deodorizing first.
You still haven't explained what the z-score of -0.5 represents. You know, the focal point of the bubble meter for 2015 that is 2 standard deviations from the z-score of house prices.
And no, a z-score cannot be calculated from a ratio. Z-scores need to be calculated from whole numbers.

Roddy, making up gibberish, and then attributing it to me as if it's something I said, is pretty transparent.
You're not going to dig yourself out of your hole this way. Even screaming about creepy clowns would be more effective.

Clueless. Hey Roddy, maybe you should call the IMF and tell them they f***ed up, because it was impossible for them to calculate Z for the rent/price ratio...
"The U.S. housing bubble of the mid 2000s was notable in that it constituted a three standard deviation event not just in valuation terms, but also in (non-price) quantity terms"
Seriously Roddy, you are so far out of your depth that it's just becoming embarrassing. Quit while you're only this far behind.

No mother cat. Chi-square distribution is not gibberish. It's also the basis by which z-scores can be calculated across different variables, much like CIti has done. The z-score might be 0; it might be 0.4; or it might be -0.5 Take your pick. The bubble meter has a z-score of -0.5 in 2015, exactly 2 standard deviations from the z-score for house prices.
Don't take it out on me. Go to Citi and try to get past security. Maybe put the costume on once you're through.

Ratios are converted to whole numbers mother cat.
Waffle. Go on Roddy, tell me again about how it was impossible for the IMF to calculate Z for the rent/price ratio...

Jesuz Terry just give it up will you! You are embarrassing yourself.....
This one is a pearler!!!

What is the point of using a z-score when you say that the Citi bubble meter is simply a measure against a 10-year average? Any old creepy clown could create that and it would be expressed as a %, not a z-score
What rubbish! A number which expresses the deviation of a value from the mean of its data set, as the number of standard deviations for that data sets distribution, is a far richer thing than a simple number stating the % deviation from the mean of its sample set!
Eg consider a normal distribution with a mean of 100 and a SD of 10. A value that was 10% higher than the mean (ie 110) would have a Z score of 1 right?
Now consider a normal distribution with a mean of 100 and a SD of 1. A value that was 10% higher than the mean (ie 110) would have a Z score of 10 right?
So both can be expressed as "a value 10% greater than the mean" - which sounds the same. But those values are VERY different with respect to the statistical distributions in question! The Z score of 1 vs 10 tells us this.
You have no hope!

Ahhh....no. Because the monitor is comprised of components over a number years. For example, consider the following:
"The truth is that there are no good men, or bad men. It is the deeds that have goodness or badness in them. There are good deeds, and bad deeds. Men are just men."
I think Roddy may have one of those weird fetishes where he needs to humiliate himself in public.
Well mother cat. A z-score of 1.5 does not represent a % increase in house prices. As my illustration shows, house prices have increased by 60%, but the z-score is 2.48. You're welcome to point out any mistakes to the calculation.
Australian Property Forum is an economics and finance forum dedicated to discussion of Australian and global real estate markets and macroeconomics, including house prices, housing affordability, and the likelihood of a property crash. Is there an Australian housing bubble? Will house prices crash, boom or stagnate? Is the Australian property market a pyramid scheme or Ponzi scheme? Can house prices really rise forever? These are the questions we address on Australian Property Forum, the premier real estate site for property bears, bulls, investors, and speculators. Members may also discuss matters related to finance, modern monetary theory (MMT), debt deflation, cryptocurrencies like Bitcoin Ethereum and Ripple, property investing, landlords, tenants, debt consolidation, reverse home equity loans, the housing shortage, negative gearing, capital gains tax, land tax and macro prudential regulation.
