NettetThe hypothesis or the model of the multiple linear regression is given by the equation: h (x) = θ0 + θ1×1 + θ2×2 + θ3×3…θnxn. Where, x i is the i th feature or the independent variables. θ i is the weight or coefficient of i th feature. Note: That x 0 = 1 and θ 0 is the bias term. This linear equation is used to approximate all the ... NettetIn multiple linear regression, the change in systolic blood pressure (ß=7.142, 95% confidence interval =4.557–9.727; P<0.0001, R 2 =0.305) was associated with ∆baPWV during follow-up. The change in glycated hemoglobin (HbA 1c ) and a glycemic control of keeping HbA 1c levels below 7.0% were not associated with ∆baPWV.
