Consider the following two regression models: (1) Yi=0+1Xi Equation (2) has been estimated using Gretl. The output is below. Model 1: OLS, using observations 1-75 const coefficient -0.4426 0.4250 std. error 0.0406 0.0244 t-ratio -10.8940 17.4090 Mean dependent var Sum squared resid R-squared F(l, 73) Log-likelihood Schwarz criterion -0.0332 6.01 0.80588 303.06 -11.768 32.171 S.D. dependent var S.E. of regression Adjusted R-squared P-value(F) Akaike criterion Hannan-Quinn p-value 0.0000 0.0000 0.6468 0.28693 0.80322 0 27.536 29.386 The sample variance of Yi is known to be 1.8669974. Calculate the magnitude (i.e. the absolute value) of the OLS estimator of '31. Show all your working.
