$13\mathrm{.}1$ Do not restructure the dataset; just follow the instructions for Problem $13\mathrm{.}2$ once the restructuring has been completed $($beginning with Click on Analyze $->$ Multiple Imputation $->$Impute Missing Data Values$).$ However, you will be using only data from Time $1$ and Time $4,$ so that you can use paired t$-$tests to look at change from Time $1$ to Time $4.$ Impute data for the following variables: weight$\mathrm{.}1,$ weight$\mathrm{.}4,$ fast$\mathrm{.}1,$ fast$\mathrm{.}4,$ binge$\mathrm{.}1,$ binge$\mathrm{.}4,$ mood$\mathrm{.}1,$ mood$\mathrm{.}4,$ preo$\mathrm{.}1,$ and preo$\mathrm{.}4.$ As before, you will use the FCS method, with a maximum of $20$ iterations and with $20$ imputations. Again, you will set the maximum percent missing to $50.$ Call the outfile imputeanorectic$3.($a$)$ How many missing values are there for weight$\mathrm{.}1,$ weight$\mathrm{.}4,$ fast$\mathrm{.}1,$ fast$\mathrm{.}4,$ preo$\mathrm{.}1,$ and preo$\mathrm{.}4?($b$)$ What are some differences between the percentage of people with values of $1,2,$ and $3$ in the original data, imputation $1($complete data, not just imputed values$),$ and imputation $20($complete data$)$ for preo$\mathrm{.}4?$
