Linear regression analysis
1] construct the linear regression formula, independent variables may be categorical or
continuous
y = β0 + β1*Deffort1 + β2*Deffort2 + β3*Deffort3 + β4*length + β5*sys + β6*gender +
β7*Dprov1 + β8*Dprov2 + β9*Dprov3 + ε
Fill in coefficients for β and heart rate for y:
Heart Frequency = 300.375 + 33.12*Deffort1 + 49.55*Deffort2 + 76.78*Deffort3 –
1.47*length + 0.66*sys – 22.44*gender – 24.71*Dprov1 – 8.0*Dprov2 – 5.65*Dprov3
2] use dummy variables in case of categorical variables
