In the cell means model parameterization of one-way anova, the regression design matrix x is such that = where ? ? is identity matrix. if one applies ridge regression shrinkage to the regression, thereby producing the parameter estimates via the formula
a. what will be the resulting cell means estimates = 1,… based on the regression parameter estimates
b. explain how does ridge regression in solving the problem multicollinearity?
= +? ? ? ?

Is there a direction u in which the rate of change of f(x, y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
