You have estimated the following moving average model. Yt= -25 + Xt - 0,5*X(t-1) The forecast origin is time T. You obtained an estimated value of X(t)=30 . What is your forecast for the observation at time t+1? -10 There is not enough information provided to estimate the forecast for the observation at time T + 1. 5 30

Imagine you have a time series-like dataset for the average weekly temperature reading for the year 2023.  We have a variable for the month numbers (month, 1-12), and one for the week numbers (week, 1-52). What commands would you need to type to get Stata to recognize this dataset as a time series dataset (with proper chronological ordering)? Group of answer choices sort month week  gen t = _n  tsset t, monthly  sort month week   gen t = _n  tsset t, weekly  tsset t  sort month week  ttset month week, weekly  sort month week  gen t = _n tsset t, weekly

Which of the following variables would be appropriate as a dependent variable in a binary logit or probit model?   (i) the binary variable for whether or not the next Star Wars movie is going to be a box-office success   (ii) the binary variable for whether or not each person goes to at least one movie in the previous month   (iii) the number of times that each person goes to the movie in the past month  (iv) the rating from 0 to 100 that each person gave to the movies seen in the last month   (v) the binary variable for whether or not each person bought something at the cinema café in the last month (ex: popcorn, drink).  Choose the most complete correct answer.  Group of answer choices (ii), (iv) and (v). (i), (ii), (iii). (i), (ii) and (v). (i), (ii), (iv), (v)

How would you generate a variable that takes on value 1 if Leia is purchased and 0 if Luke is purchased, and a missing value otherwise? Remember that in the sample, every person purchases either Luke, Leia, Anakin, or Vader (in particular, no one buys two figures, and everyone buys at least one).  Group of answer choices generate newvar = 1  replace newvar = 0 if Leia == 1   All the other options are incorrect. generate newvar = .   replace newvar = 1 if Leia== 1  replace newvar = 0 if Luke== 1  generate newvar = 1 if Leia == 1  replace newvar = 0 if Leia!= 1
