Hey! For further calculations I need to use my predicted values of my linear model. Using fitlm I get e.g. mdl =

Linear regression model: MPG ~ 1 + Weight + Year + Weight^2

Estimated Coefficients: Estimate SE tStat ________ ________ _____

    (Intercept)        54.206        4.7117     11.505
    Weight          -0.016404     0.0031249    -5.2493
    Year_76            2.0887       0.71491     2.9215
    Year_82            8.1864       0.81531     10.041
    Weight^2       1.5573e-06    4.9454e-07      3.149
                     pValue  
                   __________
    (Intercept)    2.6648e-19
    Weight         1.0283e-06
    Year_76         0.0044137
    Year_82        2.6364e-16
    Weight^2        0.0022303

Number of observations: 94, Error degrees of freedom: 89 Root Mean Squared Error: 2.78 R-squared: 0.885, Adjusted R-Squared 0.88 F-statistic vs. constant model: 172, p-value = 5.52e-41

Here I have 94 actual values, how can I get the predicted values of these? E.g if I have 94 actual prices, how can i get the predicted prices through my model (best would be in an array).

Thanks a lot!
