Suman, Im sorry not to have a straight answer. I have never seen PLR used specifically for development of prediction models. However, I could say that there is many many examples around that show no consistent advantage of more modern and complex methods over logistic regression, even if complex non linear relations among the predictors and the predictor towards the outcome are suspected. Thus, you may want to consider other stuff such as software availability and your own experience with a particular method. I suggest these readings:
1. D J Sargent, Comparison of artificial neural networks with other statistical approaches: results from medical data sets, Cancer 91, no. 8 (April 15, 2001): 1636-1642. 1. Peter C. Austin, A comparison of regression trees, logistic regression, generalized additive models, and multivariate adaptive regression splines for predicting AMI mortality, Statistics in Medicine26, no. 15 (7, 2007): 2937-2957. These readings will give the impression that the theories behind these methods bring only theoretical advantages, but do not increase accuracy of prediction when compared to logistic regression. Perhaps, if spend some time to look more around, you may be able to find evidence against this conclusion. Kind regards and good luck with your PhD.
