Fit an appropriate seasonal ARIMA model to the log-transformed Johnson and Johnson earnings series (jj) of Example 1.1. Use the estimated model to forecast the next 4 quarters. **using R** **using library "astsa" ** **using data "jj" *** the data used in example 1.1 is the same data meant to be used for this question, but for this question we are supposed to log transform it *** **** to access data: install.packages("astsa") data("so2") ****

The following data correspond to a proposal for incremental discounts. The price of component AB is $ 0.60 each in quantities of 500 or less. For quantities between 500 and 1000, they cost $ 0.58 and for quantities of more than 1000 $ 0.56 each. If the cost to place an order is $ 20, the annual demand is 800 units, and the cost to maintain inventory is 20%, it determines the quantity to buy. Q ( Cantidad) Discount %...

A model for the average price of a pound of white sugar in a certain country from August 1993 to August 2003 is given by the function S(t) = −0.00003237t5 + 0.0009037t4 − 0.008956t3 + 0.03629t2 − 0.04607t + 0.4997 where t is measured in years since August of 1993. Estimate the times when sugar was the cheapest and most expensive during the period 1993-2003. (Round your answers to three decimal places.)

The Office for National Statistics (ONS) in the UK last year proposed a new price index-a CPI that includes housing costs-called the CPIH. The rationale given for this proposal is that "the biggest cost for most homeowners is the cost of repaying their mortgage. But mortgage interest payments are not included in the CPI, nor are a variety of other costs, such as house depreciation, buildings insurance and ground rent, and house transaction costs such as estate agents' fees, survey...

An index model regression applied to past monthly returns in Ford’s stock price produces the following estimates, which are believed to be stable over time: rF = 0.1% + 1.1rM If the market index subsequently rises by 7.1% and Ford’s stock price rises by 7%, what is the abnormal change in Ford’s stock price? (Negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.)
