Hey freelancers,

I am working on a research article to forecast demand by using ARIMA and SARIMA models based on Box-Jenkins procedures (Attached).

NOTE: I need your help to understand the analysis not just doing it for me. Therefore I request the work to be done together on a shared screen.

Sor, I finished phase 2 (identification) and some parts of phase 2 (model estimation and diagnostic) which I need help for.

What I have done so far:-

- I transformed the time series to stabilize the variance.

- I differenced the time series to obtain stationarity.

These 2 steps resulted in 4 different transformed datasets.

- ACF and PACF were generated for the 4 data sets to determine AR and MA parameters.

- conducted AIC and BIC criteria to help in determining the lag for Unit root test.

What I need form the freelance for NEXT step:-

- choosing the tentative models based on unit root tests. BOTH ADF and KPSS. (+ the interpretations)

- Plotting ACF and PACF of residuals to check white noise. (+ the interpretations)

- portmanteau test of residual.

- Using the model to forecast.

Thank you,

Hasan
