What are the various confidence intervals for 2 Standard Errors v. 2 Standard Deviations from a Linear Regression Trendline or Simple Moving Average?

For instance, if I determine the value that is Two Standard Errors from a 50-day Linear Regression Trendline and I determine the value that is Two Standard Deviations from that same 50-day Linear Regression Trendline, they can't both have a Confidence Interval of 95% if they are dramatically different values; can they? By way of example, in most stock trading software, Standard Error Bands are used most often in combination with a Linear Regression Trendline and Standard Deviation Bands are used most often in conjunction with a Simple Moving Average. Can someone explain why this might be and what the different confidence intervals represent?

Sorry my last post was so confusing T_T

Here's the question:

X -> N
~X ->P
(M ^ N) -> Q
~Q
M
_____________
therefore P


I can't thank you guys ENOUGH for putting up with my stupidty!!!

For a new observatory in the Andes at 17,000 feet, we need to provide power continuously for 4 months. Requirement is 208VAC, 3 phase, 10 kW. The site is accessible by large truck, but connecting to the power grid is out of the question. We are thinking diesel generators and large fuel tanks. Any suggestions out there? Thanks.

The equation P(x)y” + Q(x)y’ + R(x)y= 0 is said to be exact if it can be written in the form [P(x)y’]’ + [f(x)y]’=0, where f(x) is to be determined in terms of P, Q, and R. The latter equation can be integrated once immediately, resulting in a first order linear eq for y that can be solved. By equating the coefficients for the preceding equations and then eliminating f(x), show that a necessary condition for exactness is P”(x) – Q’(x) + R(x) =0 . It can be shown that this is also a sufficient condition.

You don’t actually have to do this problem, but it’s supposed to help with the one I’m supposed to do.

1) x2y” + xy’ – y = 0, x>0.

How would you do this problem… or solve any exact equation

the general formula for the height H after T seconds of a projectile launched upward form ground level with initial speed V is
h = vt -1/2gt^2 where g is the gravitational constant (approximatley 9.8 m/s^2 or 32 ft/s^2)

Show that the greatest height of the projectile is (v^2) / 2g.

X -> N

(M ^ N) ->

___________
therefore P

If you don't feel like showing me every step, I'd be grateful to know where to start :)


THANKS SO MUCH~!

I had to put this equation into standard form of a parabola: f(x)=(-x^2+6x-8). The standard form is: -(x-3)^2 +1. I found that the Vertex is (3,1), and the Yint was (0,-8) because I set all the X's as 0 because I was trying to find Y. But how do I do it for the Xint? If there is only one Y? y=-(x-3)^2 -1

Sorry if I am missing it... I just don't get it.
