Linear regression analysisThe linear regression problem of a fuzzy response variable on a set of real and/or fuzzy explanatory variables is investigated. The notion of LR fuzzy random variable is introduced in this connection, leading to the probabilization of the center and the left and right ...

In particular, performances of quadratic and linear discriminant analyses, partial least squares discriminant analysis (PLSDA), and k-nearest neighbors (kNNs) were evaluated. The kNN classification rule [27] is conceptually simple: a sample is classified according to the classes of the K closest ...
Different linear combinations of L1 and L2 terms have been devised for logistic regression models, such aselastic net regularization. Random number seed: Type an integer value to use as the seed for the algorithm if you want the results to be repeatable over runs. Otherwise, a system clock v...
Partition the data into training and test sets. Use 75% of the observations to train a discriminant analysis classifier, and 25% of the observations to test the performance of the trained model on new data. Get rng("default") % For reproducibility c = cvpartition(creditrating.Rating,"Hold...
Classification is the process of finding a model that describes and distinguishes dataclass labels. A model is derived based on the analysis of a set oftraining data(objects for which the class labels are known). It is used to predict the class label of objects for which the class label is...

This paper considers the problem of testing for heteroscedasticity in the linear regression model when one is willing to postulate only the ranking of the disturbance variances under the alternative hypothesis. A new class of tests is proposed and methods of finding the tests' critical values are ...
