    (Multiple regression) Can I develop an F-test for zero-intercept?

    (Multiple regression) Can we develop an F-test for testing this hypothesis? RM : H0 : Y = e FM : H1 : Y=B0 + B1X1 + .... + BpXp + e (e : error term, r.v) As I learned, when we want to find the fitted regression equation, we should not neglect intercept part. It should not be considered zero...

    Develop Model Emulating Given Wave Pattern

    Question: Develop a model for producing a repeating pattern of 8 waves, with 6 smaller waves of approx. the same size and the second and sixth waves much larger. The sketch below gives a general indication of the eight wave pattern. (Sorry for large image) I would like to know how to "take...

    Looking to develop a good general understanding of Mathematics

    Hi guys, So I just finished my degree and I'm sad to think that it's over (it was in Accounting). I'd like to continue learning as I move into my professional career. What would be a good book or resource to start reading in my spare time on Mathematics? My aim at the moment is to just get a...

    Getting stuck on series - can't develop Taylor series.

    \frac{Log z}{sin(\pi z)} Find convergences radius at z = 1 and develop a Taylor series. Just by looking at the function I see that deviser and numerator has zeros in z = 1, so theres a limit in z = 1. The numerator isn't defined in z = 0. So the convergence radius is |z-1| < 1. (See deviser...

    Develop a function for the total number of titles l,w of rec and l of square

    I need to develop a function for finding the total number of tiles covering a floor when given the length and width of a rectangular floor and the edge length of a square tile for my programming class. I understand if a cubed tile was 1, multiplying the length and the width would giive me...

    How Do I Develop This Equation?

    I need help developing a mathematical equition that I will use to evaluate some of the financial portfolios I invest in. The end goal is to determine the probability that my portfolio will reach my maximum allowed drawdown. This will help me add and remove assets to my portfolio to get the best...

    Best way to develop your mathematical thinking.

    Okay, I'll tell you a little about me. I'm 16 year old, from Estonia. In math I think I'm in top 5-15% in my age. Well, okay that's fine, but I really want to be better. I have no problem to solve the school math exercises, but I'd be glad to be better in olympiads. The problems over there are...

    Develop algebraically an equation...

    that related the height of students arm span to their height. I have collected the arm span and height in cm of 15 students in my class and have graphed them in a scatterplot. What does it mean to develop an algebraic equation relating arm span to height? How do I go about this? Is it like...

    Develop a p series that represents a series

    find a power series that reps 1/(1+x)^3 on the interval -1,1 now we know that 1/(1+x)= x^0-x^1+x^2-x^3+x^4-x^5+... and I originally thought that I could cube each term to get 1/(1+x)^3=x^0-x^3+x^6-x^9+x^12-x^15+... to get the p series = Sigma(n=0,infinity)[(-1)^n*x^(3n)] but this I am not...
