Fitting the Fractional Polynomial Model to Non-Gaussian Longitudinal Data
Frontiers in Psychology, 2017 As in cross sectional studies, longitudinal studies involve non-Gaussian data such as binomial, Poisson, gamma, and inverse-Gaussian distributions, and multivariate exponential families. A number of statistical tools have thus been developed to deal with

SARIMA-Orthogonal Polynomial Curve Fitting Model for Medium-Term Load Forecasting
Discrete Dynamics in Nature and Society, 2016 Seasonal component has been a key factor in time series modeling for medium-term electric load forecasting. In this paper, a seasonal-ARIMA model is developed, but the parameters of the SAR and the SMA turn out to be quite nonsignificant in most cases ...

Testing fit patterns with polynomial regression models
SSRN Electronic Journal, 2015 Fit hypotheses, also labeled ‘congruence’, ‘discrepancy’, or ‘congruity’ hypotheses, contain the notion that an outcome is optimal when two predictor variables match well, while incongruent/discrepant combinations of the predictors lead to a suboptimal outcome.
