Grid adjustment question

[J Grant]

So did I, Feb. 2, 2005 in the online RealtyTimes archives. But the fact appraisers knew it did not keep Realtors from pooh-poohing the idea, and Ben Bernanke, who of all people who should have known, getting before congress as late as March 2008 and claiming there would be no contagion between the collapse of banks and the housing market. So did Ben deliberately mislead? Or was he really that stupid? Take a look at George Bush's face in some of those meetings. He was as clueless as a blind man could be. The fact WE knew it does not mean HE knew it.


Under what circumstance will we know when the AI is being distorted or not? Who gets to control AI? Or will AI eventually break its bonds and control its own future? God help us if it does.

The bias of no bias is a bias. That much I learned a long time ago. Skepticism is the sign of a scientist. Arrogance is the sign of an engineer. That's why bridges collapse and buildings fall down.

As for climate change, I am waiting for the evidence. I recently read where "climate change" had raised the oceans so high that salt water was encroaching the Amazon. Really? NOAA keeps an oceanic record, and how can one part of the ocean become higher or lower significantly from another part since it is all connected? And the NOAA records indicate the sea level has changed almost zero in the past 8,000 years. Anticipated rise in oceans for most places is measured in a few dozen millimeters in a century, and most of that cannot be discounted as being caused by changes in the land level.

And no regression analysis going to be dead to nuts outside a dense urban area.

The evidence is all around you, yet you choose to deny or ignore it.

Hopeless. There is no cure for denial.

ooops wrong thread

Well if we assume the climate scientist are correct about climate change is caused by humans, then changing humans behaviour would seem to be the best course of action. I don't think climate change is caused solely by humans. I do believe we humans are contributing to climate change. I can't find the video again but a Black Female professor said it best. She said the only way for humans to change the trajectory is to reduce the world population growth. To do that would take one to two pandemics and a world war. The order of that doesn't matter.

We humans can not stop or reverse climate change! The earths climate change existed before humans and will continue to change after all humans become extinct.

I would assume climatologists and scientists are aware that the climate existed before humans and will continue to change -after we go extinct - The point is to prevent as much catastrophic change as possible, including the degradation of habitat and the oceans to where it drives us into early extinction, or if not that, causes great suffering, and as you note, humans contribute to climate change, and thus we can change our behaviors - energy consumption, food sources etc -

I fully agree that overpopulation is a key part of the problem, and maybe the famines, floods and droughts and mass starvation that will be caused in part by climate change and other forces will wipe out enough population to be cold about it and just see it as numbers. Since people do not seem smart enough to stop reproducing in such numbers even as more jobs disappear- perhaps God created us to go extinct and leave only computer avatars or memories to show what once was -

There is no cure for denial.

Said the woman who has ever read a research article and depends upon pop science. You are the one in denial. The temperature has not changed in stations that are not impacted by the heat island effect. The oceans have not risen since the Ice ages. Gore promised us that in 2005 that the snows of Kilimanjaro would disappear by 2015...What prediction made has actually come to fruition? None. Not one. And every "model" (and models are not science, they are hypothesis) without exception indicates warmer than the actual temperature record...every single one of them. The NW Passage, which was actually open twice in the past 200 years that we know of, has not been open in years. Polar bears are increasing, not decreasing. And Greenland gets more snow than it loses in ice most years. It is still not as warm as it was in the 11th century when wheat was grown there.

And often the media exaggerates what scientists say...making ridiculous claims like below when the media claimed last summer was the hottest year ever in the UK....not even close.

then why do they start their time line at 1970? 50 years. You know why. Because the 70s were cold - natural climate variation. If they started in 1910, then it would look like we are, in fact, much cooler because the teens, 30s and 50s were much hotter which means a trend line for the past 120 years (which is easy enough to do) would trend down, not up.)

In order to try and set a new world record high temperature, they moved the Death Valley meteorological station to an even lower elevation and placed it near a rock wall which will add a couple degrees to the readings. It was embarrassing to true believers that the record has stood for more than 100 years.

The new weather station is at an elevation of 219 feet below sea level. This is 26 feet lower than a similar automated weather station located at Furnace Creek Visitor Center (-193 ft). The Campbell Scientific weather station measures temperature, humidity, and rainfall.​

I will not respond after to this wrt climate change on this tread it is off topic - but since you posted over three times your usual-I'll rely on NASA and the world's premier scientists and climatologists I'll take their expertise and the evidence unfolding all around us as what to rely on - end of my responding it is bad enough it took up this much space ona thread about appraisals.

Wow this post went from interesting support or the lack of support and tools for adjustments to climate change, that was a good read!

 

[alebrewer]

All I know, is I have not seen a single appraisal... in the last 20 plus years of appraising...that had utilized MARs regression that included charts and graphs with commentary / explanations justifying its use for any sort of adjustment. Not one.

I've seen Excel, Synapse, Solomon, Trendsheet4
Shoot....even Appraisal Genie. I keep hearing how great Mars is but I've never seen it.

I personally use MiniTab. MUCH easier to run regressions than Excel. If you get an older version it's not that expensive either. I think I paid around $150 for v17 a couple of years back.

Refresh my memory. Where does it say we must have a good understanding of how regression works before we can use it in our analysis and reporting?


I use and have used many times the HP-12C. It comes with an owners Handbook and problem solving guide. So I am familiar with it and know it can do quite a bit of mathematical problem solving.
