TimeSeries and Forecasting

Inthe time series, there are challenges in understanding and applyingthe concept in solving mathematical problems and in the practicalsense. One of the greatest challenges that I face is using the excelcalculation formulae to solve time series problems. I am particularlychallenged in calculating the time series problems using the excelspreadsheet methods to develop the time series analysis. I find thischallenging because of the complexity of the excel spreadsheetformulae. Another challenge I face is interpreting the results of thetime series analysis and applying it in the real life. I find itchallenging because of the limitations of the practicality of some ofthe problems.

Tohelp me with these challenges, I found the Microsoft excel Tutorial asignificant guide towards understanding the use of excel formulae.After studying for a while, I found the tutorials viable and a veryhelpful resource for learning prowess in spreadsheet calculations. Atthe same time, I find the book by Henrik Madsen,asa good resource for learning more about the application of timeseries results (Madsen,2007).Through the book, I will be able to understand the use of the resultsof a time series problem and apply them in the practical world.

Inthe real world, forecasting is used to make decisions about sales andbusiness performance in commerce. I worked at a restaurant for ashort while as an intern in the management. I could see theapplication of time series in predicting sales for the restaurant byusing the number of tables and the number of seats as the variablestowards the sales. I participated in the estimation of sales on anactive day, where we used to estimate the sales figure by consideringthe tables, seats and the time each customer spent at the restaurant.
