Summary Introduction

To determine: The graph from data of first six months of 2013 and to estimate the regression parameters -slope and intercept from that graph.

Introduction: Regression analysis is a forecasting method that specifically accounts for a trend in the data. It suits a straight line with a data set.

b)

Summary Introduction

To determine: The exact values of the intercept a and the slope b from the regression equation

Introduction: Regression analysis mainly accounts for a trend in data between dependent and explanatory variables. When applying regression analysis to forecasting problem, explanatory variable often corresponds to time and dependent variable to the series to be forecasted.

(c)

Summary Introduction

To determine: The forecasts obtained for July through December 2013 from the determined regression equation

Introduction: Forecasting is done based on previously observed data. Assuming first six months/periods of 2013 as baseline, forecasted values for rest periods of the year can be attained.

(d)

Summary Introduction

To explain: Reassessment on the forecasts made for July to December of 2013.

Introduction: The least square method assumes linear relationship between the variables.Linearity implies it can be illustrated as a straight row graphically. Linearity assumption may be violated in reality.

28. Shoreline Park in Mountain View, California, has kept close tabs on the number of patrons using the park since its opening in January 1993. For the first six months of 2013, the following figures were recorded: Month Number of Patrons Month Number of Patrons April May June 640 January February March 133 183 1,876 2,550 285 a. Draw a graph of these six data points. Assume that January February fit of the data. Estimate the slope and intercept from your graph. period 1, period 2, and so on. Using a ruler, “eyeball" the best straight-line +

Room registrations in the Toronto Towers Plaza Hotel have been recorded for the past 9 years. To project future occupancy, management would like to determine the mathematical trend of guest registration. This estimate will help the hotel determine whether the future expansion will be needed. Given the following time-series data, develop a regression equation relating registrations to time (e.g., a trend equation). Then forecast year 11 registrations. Room registrations are in the thousands: Sr. No Year Registration (000) 1 2011 17 2 2012 16 3 2013 16 4 2014 21 5 2015 20 6 2016 20 7 2017 23 8 2018 25 9 2019 24

The monthly sales for Yazici Batteries, Inc., were as follows: Month Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov Dec Sales 19 21 17 15 15 18 16 19 22 20 20 24 This exercise contains only parts b and c. b) The forecast for the next month (Jan) using the naive method = 24 sales (round your response to a whole number). The forecast for the next period (Jan) using a 3-month moving average approach = 21.33 sales (round your response to two decimal places). The forecast for the next period (Jan) using a 6-month weighted average with weights of 0.10, 0.10, 0.10, 0.20, 0.20, and 0.30, where the heaviest weights are applied to the most recent month = 20.9 sales (round your response to one decimal place). Using exponential smoothing with a = 0.40 and a September forecast of 18.00, the forecast for the next period (Jan) = sales (round your response to two decimal places).
