2.6. Statistical analysis
Drying kinetics data of the samples were analyzed using Statistica
6.0 software.
Nonlinear regression analysis was performed based on the Levenberg–Marquardt algorithm to calculate corresponding parameters of the models mentioned in Table 2.
Validation of the statistical models was determined using R2,
χ2 and RMSE values calculated using the following equations yexp,i and ypred,
i are the experimental and predicted MR values of ith observation,
and n andm are the observation number and number of constants
in the corresponding model
