109 is a widely used statistical method for analyzing data using two categorical responses. Instead of providing a yes or no answer to the predictions for crack initiation, the probability of a pavement to crack under a particular condition (material, environment, structure, etc.)

110 Details of each step are provided below using transverse cracking model development as an example. Data Collection The potential data that could correlate with transverse cracking are given in Chapter 3.

111 is considered to be highly correlated (multicollinear) with the other predictor variables.

112 Determination of Model Coefficients Standardized coefficients for each predictor variable were determined using Minitab software to perform PLS regression analysis. Standardized coefficients identify the importance of each predictor variable in the model.

113 the omitted response. The LOOCV then predicts the omitted response using the recalculated model and calculates the residual value.

115 Arbitrary values were assigned to two groups of pavement transverse cracking: 0.02 for pavement sections without cracking (yi = 0.02) and 1.0 for pavement sections with recorded cracking (yi = 1)
