Forecasting gold prices in India using an ARIMA model

Over the years, the gold prices have been increasing rapidly. Covid-19 and its impact leads to rise in the prices of Gold in the year 2020. So many variables are mindful for increasing the gold cost in India and it leads to investment decisions of individuals and enterprises. Autoregressive Integrated Moving Average (ARIMA) is useful method to gauge time series data. In the paper we mainly focus on daily costs of Gold from the year 2018 to 2020 to determine and forecast the daily gold prices in 2021. Also estimate the error (%) between the observed and estimated values through ARIMA model. This study will provide the estimates of suitable ARIMA model (0,1,2) along with Autocorrelation function (ACF) & Partial autocorrelation function (PACF) from the selected data, The auxiliary source information shows the positive patterns for getting effectiveness, For quantitative examination and speculation selections of financial backers. © 2023 Author(s).

A Review of Guidelines to Resuming Elective Orthopaedic Surgeries Amid COVID-19 Pandemic: Deriving a Simple Traffic Light Model.

The COVID-19 pandemic has affected most healthcare systems around the world. Routine care operations such as outpatient clinics and elective surgery remain badly hit. This situation cannot continue for long as it puts patients at a higher risk for complications due to delayed management. Hence, it is essential to resume routine, especially elective surgery. Regarding orthopaedic practice, various authors and organisations have come out with guidelines to resume elective surgeries. However, clear consensus and common strategies need be derived. With this motive, we conducted a review of the literature for guidelines to resume elective orthopaedic surgery amid COVID-19 pandemic and shortlisted scholarly publications and information from regional organisations. We have summarised the information and derived an organised algorithm considering the guidelines provided by various sources. In this extraordinary time, guidelines come in as a relief for every surgeon who is in a dilemma whether to resume electives or not. Putting safety first, these guidelines or suitable versions should be followed at all levels wherever possible to avoid the lack of trained manpower in the event of staff morbidity.
