• Feb 18, 2020 · What does an r2 value of 1 mean? R 2 is a statistic that will give some information about the goodness of fit of a model. In regression, the R 2 coefficient of determination is a statistical measure of how well the regression predictions approximate the real data points. x^2 +h^2 = r1^2 (d-x)^2 +h^2 = r2^2 ==> h = sqrt(r1^2 - 1/d^2*(r1^2-r2^2+d^2)^2) i.e. you can solve for h, which is the radius of the circle of intersection. You can find the center point C of the circle from x, along the line N that joins the 2 circle centers. Then you can fully describe the circle as (X,C,U,V are all vector)

# 1 point consider a linear transformation t from r3 to r2 for which

Let TA : R2 R3 be the matrix transformation corresponding to Find TA (u) and Where And View Answer Let T be a linear transformation from R2 to R2 (or from R3 to R3). Prove that T maps a straight line to a straight line or a point. The word "linear" in "multiple linear regression" refers to the fact that the model is linear in the parameters, $$\beta_0, \beta_1, \ldots, \beta_k.$$ This simply means that each parameter multiplies an x-variable, while the regression function is a sum of these "parameter times x-variable" terms. EXAMPLE 1.7 Consider the curve FðtÞ ¼ ½sin t; cos t; t in R3 . Taking the derivative of FðtÞ [or each component of FðtÞ] yields V ðtÞ ¼ ½cos t; À sin t; 1 which is a vector tangent to the curve. We normalize V ðtÞ. First we obtain kV ðtÞk2 ¼ cos2 t þ sin2 t þ 1 ¼ 1 þ 1 ¼ 2 Let T : V → V be a linear transformation such that the nullspace and the range of T are same. Show that n is even.
