The optimal weights for ARMA and ES models are 0.529 and 0.471 respectively, And the value of the error variance of the combined model is 15.656.
Let w1 be the weight of ARMA model and w2 be the weight of ES model.
We know that the sum of weights is equal to 1.i.e. w1 + w2 = 1
Also, the variance of the error of the combined model is given by
σc² = w1²σARMA² + w2²σES² + 2w1w2σARMAσESρ
where σ
ARMA² = 16σES² = 25ρ = -0.9σc² = w1²(16) + w2²(25) + 2w1w2(4.5)
For the combined model to have the minimum variance, the partial derivatives of σc² w.r.t.
w1 and w2 should be equal to 0.∂σc²/∂w1 = 32w1 + 9w2 - 36w1 = 0∂σc²/∂w2 = 50w2 + 9w1 - 45w2 = 0
Solving the above equations, we getw1 = 0.529, w2 = 0.471
Therefore, the optimal weights for ARMA and ES models are 0.529 and 0.471 respectively.
The variance of the error of the combined model is
σc² = w1²σARMA² + w2²σES² + 2w1w2σARMAσES
ρ= (0.529)²(16) + (0.471)²(25) + 2(0.529)(0.471)(-3.6)= 7.947 + 11.675 - 3.966= 15.656
The value of the error variance of the combined model is 15.656.

Which box on a W-4 notes an employee's filling status?
Box number 3 on a W-4 notes an employee's filling status?
What is a W-4?
An IRS form known as a W-4, also known as a "Employee's Withholding Certificate," instructs employers how much tax should be deducted from each employee's paycheck. Employers utilize the W-4 to calculate some payroll taxes and remit the taxes on behalf of employees to the IRS and the state (if applicable).
If your employer already has a copy of your W-4 form on file, you do not need to fill one out again. Additionally, you are not required to complete a new W-4 annually. But you'll probably need to complete a new W-4 if you start a new employment or wish to change the withholdings at your current position. In either case, it's a good justification for reviewing your withholdings.

Question 1 : A company’s fixed costs are $60,000 and variable costs per unit are $4. The sales price is $10. The company sold 12,000 units. Which of the following is the company’s margin of safety percentage?
The margin of safety percentage for a company can be calculated by determining the difference between the actual sales and the breakeven sales, and then dividing it by the actual sales. In this case, the fixed costs are $60,000, the variable cost per unit is $4, and the sales price is $10. The company sold 12,000 units.
To calculate the breakeven sales, we need to determine the breakeven point where the company covers all its costs. The breakeven point can be calculated by dividing the fixed costs by the contribution margin per unit, which is the sales price minus the variable cost per unit.
In this scenario, the contribution margin per unit is $10 - $4 = $6. Therefore, the breakeven point can be calculated as $60,000 / $6 = 10,000 units.
The margin of safety is the difference between the actual sales (12,000 units) and the breakeven sales (10,000 units), which is 2,000 units. To calculate the margin of safety percentage, we divide the margin of safety by the actual sales and multiply by 100.
Margin of Safety Percentage = (Margin of Safety / Actual Sales) x 100
= (2,000 / 12,000) x 100
= 16.67%
Therefore, the company's margin of safety percentage is approximately 16.67%.
