How on earth are you getting that? First, the math is not fuzzy, it's pretty rigorous. Just because YOU don't understand statistics doesn't mean the math is fuzzy.
Second, I've said nothing to imply that I have any political preferences. I was saying the same things when Bush was president and idiot Liberals were trying to say the numbers were fudged.
Just because you're blindly partisan doesn't mean everyone else is.
If it's rigorous why is there any need to come back and revise the numbers?
Because the data isn't complete. The household survey numbers are NOT revised but a lot of other datasets are. Empolyment (non-farm payroll jobs) comes from a survey of businesses where, after initial contact, the establishments call/fax/email their employment numbers every month they're in the survey. The December numbers come out next week, so let's look at the process. The reference period is the Pay Period that contains the week of December 11-17 and reporting started December 18.. But if the pay period doesn't end until the 24th, the numbers won't be in on time. Or some establishments are lazy or forgetful and don't report on time.
Additionally, every March, BLS looks at the full list from UI records on employment for all companies registered with UI. That takes a few months to process and the result will not exactly match the March estimate. So with the new benchmark, the numbers are revised.
The revisions go both ways...there's no pattern of making things look better or worse, and the revisions are generally small (biggest adjustment I've seen was 0.7%, and the average is much smaller).
How? How do you think they could get all the data collected on time? How do you think an estimate will always exactly match a full count?
I've said nothing to imply that I have any political preferences. I was saying the same things when Bush was president and idiot Liberals were trying to say the numbers were fudged.
This is news to me. you aren't a liberal? Maybe you need to revise some of your other post.
Example? I have some liberal and some conservative views. I'm an extreme Centrist.
