The sales trend has been modeled as: Sales=3.00 * t + 122.00, where t = time in quarters

The sales trend has been modeled as: Sales=3.00 * t + 122.00, where t = time in quarters, beginning in Q1 2015. Seasonality for the four quarterly periods is given in the table below. Find the seasonalized forecast for Q1 of 2017.

Quarter	Seasonal Factor
Quarter #1	1.10
Quarter #2	0.9000
Quarter #3	0.9000
Quarter #4

Answer format: Number: Round to: 1 decimal places.

Expert Solution

1.

De-seasonalized forecast for Qtr 1 2017 = 3 * t + 122 = 3*9+122= 149

Seasonalized forecast for Qtr 1 2017 = 149 * SI for Qtr 1 = 149*1.1 = 163.9

The life time of a dryer machine can be modeled with the probability distribution , where x is the time in years and beta is an unknown parameter. Findings that 3 machines life time are after x1, x2, x3 years. 1. what is the likelihood function? 2. assume the observations are x1 = 5, x2 = 6, x3 = 5. Use this information and simplify the likelihood function as much as possible. 3. what is the log-likelihood function, simplified as...

Time series decomposition seeks to separate the time series (Y) into 4 components: trend (T), cycle (C), seasonal (S), and irregular (I). What is the difference between these components? The model can be additive or multiplicative.When we do use an additive model? When do we use a multiplicative model?

Brain weight B as a function of body weight W in fish has been modeled by the power function B = 0.007W2/3, where B and W are measured in grams. A model for body weight as a function of body length L (measured in centimeters) is W = 0.12L2.53. If, over 10 million years, the average length of a certain species of fish evolved from 13 cm to 21 cm at a constant rate, how fast was this species' brain...
