Find the point of intersection of the lines x = 2t + 1, y = 3t + 2, z = 4t + 3 and x = s + 2, y = 2s + 4, z = -4s - 1, and then find the plane, in linear form, determined by these lines. (i.e Find the shortest...
The sum of squares is a statistical measure of variability. It indicates the dispersion of data points around the mean and how much the dependent variable deviates from the predicted values in regression analysis. We decompose variability into thesum of squares total(SST), thesum of squares regre...
