Amit;

How about this; make 10 predictions per month.

You'll be almost 100% correct.

Hi
6.8 quake on 5th Jan 2019 at Brazil against 7.2 predicted. A hit major prediPredi

Amit;

2 quakes today actually, one in Brazil, the other in the Aleutians. You shouldn't predict mag without a range if you want credit for a hit. I've been ignoring it but that could change.

I'm using my year lists to check your predictions from 2010 to 2017 but I want to revise the program to add your windows. Doing it by hand is so tedious!

I'm using a simplified calculation whereby odds are window days divided by days in the year. It's reasonable. If you cover 25% of the days you should get 25% of the quakes.

You seldom do that well which is why I say "Just chance".

Thank you very much for your efforts.
I have already checked randomly ( without any software) that ..
I usually cover 25 to 30 % of windows in month and 60 to 80 % quakes occur in my window. You can cross check it
I do give magnomagn window , + or - 0.3
I am sure ,ifif you can include magnitude windows with time windows ,I am much much better than odds

One more
6.6 quake at zindonesis on ,6th ,a date hit Prediction

Roger
One more quake
6.6 at Indonesia on 6,the, a date hit Prediction

If you consider ,% of window period and total month period ratio to that of quakes occured in my windows to total quakes ,I am far far above the odds

Amit;

Mag. is a problem when there is more than one quake in a window.

Wow, superb blog layout! How long have you been blogging
for? you make blogging look easy. The overall look of your
site is great, as well as the content!

Hi
Watch out
6.7 quake at Chile today ie 20th January 2019 ,as against 21st predicted on 21st
Is this just coincidence?
Amit

Roger Hunter said...

Amit;

I need a list of aspects and distances that you use in making your predictions.

With it, I'll be able to duplicate those conditions for the list of quakes I sent, which will tell us how often they apply.

I can't find it on your website.

Ok

Roger Hunter said...

Amit;

Excellent! Just what I needed.

Roger

Roger Hunter said...

Amit;

I'm sorry, my program doesn't give distances except for sun and moon, so I can't duplicate your predictions.

How do you get them?

Roger

AMIT said...

Hi
One more hit .6.7 at Prince Edward region on 22nd.
Three major 6.5+ quakes I .a window
Amit

Roger Hunter said...

Amit;

Ok, what about the 5 you missed?

I found a source for distance so I'll be able to continue my testing but it only goes back to 2011 and it'll take a long time. Lots of downloading and editing to do.

Roger

Roger Hunter said...

Amit;

I now have a file containing RA, Dec, and distance from earth for Sun, Moon, Venus, Mars, Jupiter and Saturn for every day from 2014 to 2018.

With this I can compute geocentric angles.

Next I'll add quake days for mag 6+ quakes

What all would you consider important to your predictions?

Roger
Roger

Roger Hunter said...

Amit;

I've added 6+ quakes and your prediction days to the array.

Results show that 660 of the 1826 days were predicted days, giving 0.361 chance of success.

There were 547 quake days and 246 hit days.

These results can be obtained by chance about 28% of the time which is not good enough to prove ability.

That being the case I see no reason to look further into your planetary speculations.

Roger

Roger Hunter said...

Amit;

Would you like a copy of my results so far?

Every day for 5 years, 23 columns per day. Makes for a pretty big file.

Roger

PS: available to anyone by request.

It is in point of fact a great and useful piece of information. I'm glad that
you shared this useful information with us. Please stay us up to
date like this. Thanks for sharing.

AMIT said...

Yes pl
Need a copy

AMIT said...

Roger
Total 547 quake days in total 1826 days.Thus chace of quake is
547÷1826=0.299

Where as my hits were 246 days in 660 days I have predicted.
So my results are

246÷660=0.377

Which is much better than odds (0.299)

Roger Hunter said...

Amit;

Yes, you were a bit better than chance but not enough better to depend on.

You can't evacuate a city when there's a 28% chance it's a false alarm.
That's why my evaluation program requires a 99% significance level.

Roger

Roger Hunter said...

Amit;

Something you might try; examine the factors you use in making your predictions to see if any of them could be eliminated to reduce the number of false predictions.

I had intended to do this with my program but things like "closest" can be difficult to define to a machine.

Roger

AMIT said...

Hi
Here it is.6.6 quake at Maxico today ie 1st Feb 2019, in window period.
Is this a fluke or by chance?
Amit

AMIT said...

Roger
Forget earthquake prediction ,science can not predict weather and rain with 99% accuracy of place and inches of rain ,with all those super computers and satellite images
Amit

Roger Hunter said...

Amit;

Such accuracy is not important for weather forecast.

It is vital for earthquakes that may destroy cities.

Where are your Feb windows?
