[pdf] The results of the experimental study for the compressive strength and the abrasivity of the rock samples are given in Table 1. It is seen that, with increase in compressive strength abrasivity of rock samples also increases. This may be attributed to increase in the resistance of rocks to wear with increase in the. .
Regression analysis is the statistical methodology for predicting values of one or more dependent variables from a collection of (independent) variables.. .
The coefficient of correlation between the measured and predicted values is a good indicator to check the prediction performance of the model. In this study, values.
