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.
