Regression with weird distribution

No.14191740 ViewReplyOriginalReport
Hi /sci/, I'm trying to predict a variable that has a weird distribution and when I run OLS I get a set of significant predictors but low R^2. (picrel, it's returns for a highly volatile asset).

I've tried doing a log-log regression but that didn't work. My independent variables are mainly either categorical or highly skewed (exponential with many observations being 0). What should I do?

Rickover

This man revolutionized the supply chain of the navy , developed the NNPP with such a high standard that has proven track record of zero reactor accidents. Doing all of this while enduring immense opposition , being routinely held up in rank and having intense pressure from the shipyards and other navy officials for him to fade into existence.


Developing the Genius sidestep of self regulation with NR instead of the grossly incompetent NRC was a god teir move. shipyard with hands in the pockets of Reagan forced him to retire was disheartening to say the least.

How does /sci/ remember this recipient of not one but two Congressional gold medals ( among the likes of Robert frost , the Wright brothers etc )? As raving lunatic towards the end of his life , or an Engineering visionary developing a program that still produces leaders in the field?

When can you scientifically/medically say you're partly another race?

Say you are a white person who got a blood transfusion from a Native American. Could I now call myself part Native American??? After all I probably would have more Native American blood in me at that point than so called "Native Americans".
Or what if I got a skin graft from an asian man. Could I call myself part asian?
If no to either of those then what if I got a heart transplant from a black man? Would I not be part black?

This is probably really fucking stupid to ask but I am wondering this unironically.
What would it take for me to be allowed to change the "what race are you" boxes on a census?

what determines the absorption spectrum for a substance?

No.14191806 ViewReplyOriginalReport
What determines why a specific absorption spectrum is the way it is other than the atomic composition of the substance? For instance, haemoglobin and oxyhaemoglobin only differ by a single oxygen yet that is enough to cause a dip in the absorption spectrum at 575nm. Another example is that despite the fact that biliverdin and bilirubin are pretty much identical in atomic composition, biliverdin is green yet bilirubin is yellow/brown.

Obviously molecular structure and different bonds have to play a role, but I can't find an explanation geared towards laymen as to why this might be, I only found an explanation relating to the energy levels of the different atoms in the substance.

Where can I read more about this? I tried looking around but could not find a good place to start.

You're not going to miss out on the quantum revolution, are you, Anon? You *are* learning quantum computing, right?

Labor Unions for Engineers

No.14187242 ViewReplyOriginalReport
What are the implications of professional engineers forming labor unions? I think there is a misconception that white collar professionals will be adequately compensated by (((corporations))) if they work hard and try to get ahead in the rat race. However, I think that unionization would provide a higher standard living for everyone. First of all, a union would force clients to pay a minimum rate for engineering services. Also, with collective bargaining, a union could ensure that nobody works overtime without receiving compensation ever again. However, I think that the most compelling argument might simply be that the labor market today is a vastly different animal than it was a few decades ago. Times are changing, and, while professions that require licensure were once somewhat protected against deteriorating employment conditions, the modern industry professional is now just as exploitable as any blue-collar worker.

P.S. Here is some food for thought. It seems like most professional engineering organizations tend to discourage unionization out of fear that a union engineer "is under extreme practical pressure to conform to the group, or risk an unpleasant and disruptive work relationship."

When did right wing chuds take over this board? This board has become the complete rejection of science and how we shouldn't trust scientists anymore. As an example it's crazy to see the right wing chuds here outright reject the notion of dinosaurs having feathers because when they watched their favorite childhood Hollywood movie Jurassic Park the fictional dinosaurs there didn't have feathers in the movie lol.
