Machine Learning Modelling in R : : CHEAT SHEET

Classification: Accuracy, precision, Simple models with ew parameters areeasier to compute but lead to poorer fits (high bias). Complex models more fits but over-fit the data 'high variance) Cross validation compares the test performances of different model realisations with different sets or values of parameters

January xxxxxx Time Zones R recognizes ~600 time zones. Each encodes the time zone, Daylight Savings Time, and historical calendar variations for an area. R assigns one time zone per vector. Use the UTC time zone to avoid Daylight Savings. OlsonNames() Returns a list of valid time zone names. OlsonNames() Sys.timezone() Gets current time zone.

The ARIMA Procedure

ARIMA model includes other time series as input variables, the model is sometimes referred to as an ARIMAX model. Pankratz (1991) refers to the ARIMAX model as dynamic regression. The ARIMA procedure provides a comprehensive set of tools for univariate time se-ries model identification, parameter estimation, and forecasting, and it offers great

3 Construction of an ARIMA model 1. Stationarize the series, if necessary, by differencing (& perhaps also logging, deflating, etc.) 2. Study the pattern of autocorrelations and partial autocorrelations to determine if lags of the stationarized series and/or lags of the forecast errors should be included

The Box-Jenkins Method

where is the order of differencing. This is known as the d ARIMA(p,d,q) model. 2. Fit a least squares trend and fit the Box-Jenkins model to the residuals. If the model exhibits an occasional change of mean, first differences will result in a stationary model.

Enhancing the Locality and Breaking the Memory …

One of the most prominent models is ARIMA [15]. Its statistical properties as well as the well-known Box-Jenkins methodology [16] in the model selection procedure make it the first attempt for practitioners. However, its linear assumption and limited scalability make it unsuitable for large-scale forecasting tasks.
