- I need Strain-displacement MatrixSuppose we are doing ordinary least-squares linear regression with a fictitious dimension. Which of thefollowing changes can never make the cost function’s value on the training data smaller? A: Discard the fictitious dimension (i.e., don’t append a 1 to every sample point). B: Append quadratic features to each sample point. C: Project the sample points onto a lower-dimensional subspace with PCA (without changing the labels) andperform regression on the projected points. D: Center the design matrix (so each feature has mean zero).Find the least squares regression line for the points (−3, 0), (−1, 1), (0, 2), and (2, 3).
- Find the least square regression line.Find dX/dt of Matrix:The coefficient matrix is not strictly diagonally dominant, nor can the equations be rearranged to make it so. However, both the Jacobi and the Gauss-Seidel method converge anyway. Demonstrate that this is true of the Gauss-Seidel method, starting with the zero vector as the initial approximation and obtaining a solution that is accurate to within 0.01.
- For a system of 3 equations using FGLS where I imposed a restriction on omega_hat that the residuals, u1 and u2 are uncorrelated, but u1 and u3 are correlated. How do you estimate/code omega in SAS using FGLS given the conditions above?I need find fundemental matrix for ODEShow the LU Decomposition. Must show the Lower and Upper Matrix
