We fit a lasso model to some data for λ=10 and λ=100 and we obtain the coefficients vector estimates b1 and b2 respectively. Then The L1 norm of b1 is less or equal to the L1 norm of b2. b1 is either more sparse than b2, or as sparse as b2. The L1 norm of b2 is less or equal to the L1 norm of b1. b2 is either more sparse than b1, or as sparse as b1.

In R, write a function that produces plots of statistical power versus sample size for simple linear regression. The function should be of the form LinRegPower(N,B,A,sd,nrep), where N is a vector/list of sample sizes, B is the true slope, A is the true intercept, sd is the true standard deviation of the residuals, and nrep is the number of simulation replicates. The function should conduct simulations and then produce a plot of statistical power versus the sample sizes in N for the hypothesis test of whether the slope is different than zero. B and A can be vectors/lists of equal length. In this case, the plot should have separate lines for each pair of A and B values (A[1] with B[1], A[2] with B[2], etc). The function should produce an informative error message if A and B are not the same length. It should also give an informative error message if N only has a single value. Demonstrate your function with some sample plots. Find some cases where power varies from close to zero to near…

Consider a dataset D1 with 150 samples, labeled using two labels, L1 and L2; out of 150 samples, 26 are labeled with L1 and 124 are labeled with L2 (this is the ground truth). Consider a dataset D2 with 50 samples, also labeled using L1 and L2 as labels; out of 50 samples, 39 are labeled with L1 and 11 are labeled with L2 (this is the ground truth). Compute the gini index of the combined dataset and the gini indices of each dataset D1 and D2.

I need help with my MATLAB code. I am using ode45 to solve my differential equation. But, the size of w_ode is 9x645. Size of t is also 1x645. How is that possible? Shouldn't t be 1x101 and w_ode be 9x101? How do I get the size to be 9x101? I need that size because I am subtract that matrix by another matrix of the same size.
