Model specification (p.6): LN(MRP) = b0 + b1 LN(RPP) + b2 NBR + b3 LN(RPS) + ENV + ESS + COL + POS + DIS + interactions, so dependent = log monthly rent and size enters in logs; but constant 143.58 and MSE 1507 suggest the fitted model may be in rent levels — dep_transform ambiguous. Text narrative (p.8) quotes different numbers from Table 2 for size (b=0.07,t=2.26), political stability (-0.08,-2.48), displacement (0.07,2.18), interaction1 (0.21,3.52); Table 2 values used. Non-characteristic regressors not extracted: Residential property price (RPP) 0.02 (t 0.61), Cost of living -0.26 (-4.85***), Political stability -0.02 (-0.66), Displacement 0.05 (1.26), Interaction1 rent x cost of living 0.25 (4.49***), Interaction2 rent x essential services 0.67 (12.24***).
