Inicio Educación. Using SAS Forecast Server Procedures This course teaches you how to create and manage a complete forecasting system using the SAS Forecast Server procedures, giving you the power to confidently plan your business operations. Time Series Modeling Essentials This course discusses the fundamentals of modeling time series data.

The course focuses on the applied use of the three main model types used to analyze univariate time series: exponential smoothing, autoregressive integrated moving average with exogenous variables ARIMAXand unobserved whwt UCM. The e-learning format of this course includes Virtual Lab time to practice. Aalysis Series Feature Mining and Creation In this course, you learn about data exploration, feature creation, and feature selection for time sequences.

The topics discussed include binning, smoothing, transformations, and data set operations for time series, spectral busiiness, singular spectrum analysis, distance measures, and motif analysis. Linear regression, Poisson regression, negative binomial regression, gamma regression, analysis of variance, linear regression with indicator variables, analysis of covariance, anzlysis what is regression analysis used for in business models ANOVA are presented in the course.

Stationarity Testing and Other Time Series Topics This course addresses a basic question in time series modeling and forecasting: whether a time series is nonstationary. This question is addressed by the unit root tests. One of the most common tests, the Dickey-Fuller test, is discussed in this lecture. Students are presented with an overview of the model and learn advantages of the State Space approach. The course also describes fundamental model details, presents some straightforward examples of specifying and fitting models using the SSM procedure, and considers estimation in SSM, focusing on the Kalman filter and related details.

The course concludes with a variety of SSM modeling applications, focused mainly on time series. Models for Time Series and Sequential Data This course teaches students to build, refine, extrapolate, and, in some cases, interpret models designed for a single, sequential series. There are three modeling approaches presented. The traditional, Box-Jenkins approach for modeling time series is covered in the busuness part of the course.

A Bayesian approach to what is regression analysis used for in business time series is considered next. The basic Bayesian framework is extended to accommodate autoregressive variation in the data as well as dynamic input variable effects. Machine learning algorithms for time series is the third approach. Gradient boosting and recurrent neural network algorithms are particularly well suited for accommodating nonlinear relationships in the data.

Examples are provided to build intuition on the effective use of these algorithms. The course concludes by considering how forecasting precision can be improved by combining the strengths of the what is regression analysis used for in business approaches. The final lesson is love worth it quotes demonstrations of creating combined or ensemble and hybrid model forecasts. Establishing Causal Inferences: Propensity Score Matching, Which equation is not a linear function iready Two-Stage Model, Interrupted Time Series, and Regression Discontinuity Models This course introduces some methods commonly used in program evaluation and what is regression analysis used for in business effectiveness studies, including two-stage modeling, interrupted time-series, regression discontinuity, and propensity score matching.

These methods help address questions such as: Which medicine is more effective in the real world? Did an advertising program have an impact on sales? More generally, are the changes in outcomes causally related to the program being run?
