Starting with the SASHelp data set, Sales, create a temporary SAS data set (call it Sales) that contains a variable (call it Date) that is a SAS date by using the three variables Month, Day, and Year (remember the MDY function). Be aware that the original SASHelp data set also contains a variable called Date, but it is not a SAS date. You can drop the original Date variable with a DROP= data set option on the SET statement when you bring in data from the SASHelp data set. Next, generate a time series plot with Date on the x axis and Sales on the y axis. It should look like this:<\/p>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To create a temporary SAS data set named Sales<\/code> that includes a SAS date variable derived from the existing Month<\/code>, Day<\/code>, and Year<\/code> variables, and then generate a time series plot with Date<\/code> on the x-axis and Sales<\/code> on the y-axis, follow these steps:<\/p>\n\n\n\n

    \n
  1. Create the Sales<\/code> Data Set with a SAS Date Variable:<\/strong> Use the MDY<\/code> function to combine the Month<\/code>, Day<\/code>, and Year<\/code> variables into a new variable Date<\/code>. The MDY<\/code> function returns a SAS date value from the specified month, day, and year. \ue200cite\ue202turn0search2\ue201<\/li>\n<\/ol>\n\n\n\n
       data Sales;\n       set sashelp.sales(drop=Date);\n       Date = mdy(Month, Day, Year);\n       format Date date9.;\n   run;<\/code><\/pre>\n\n\n\n
    In this code:<\/p>\n\n\n\n
      \n
    • set sashelp.sales(drop=Date);<\/code> reads the sashelp.sales<\/code> data set and drops the existing Date<\/code> variable to avoid conflicts.<\/li>\n\n\n\n
    • Date = mdy(Month, Day, Year);<\/code> creates a new Date<\/code> variable by combining Month<\/code>, Day<\/code>, and Year<\/code>.<\/li>\n\n\n\n
    • format Date date9.;<\/code> formats the Date<\/code> variable to display in the date9.<\/code> format (e.g., 28FEB2025).<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Generate the Time Series Plot:<\/strong> Use the SGPLOT<\/code> procedure to create a time series plot with Date<\/code> on the x-axis and Sales<\/code> on the y-axis. The series<\/code> statement plots the data points connected by lines, which is suitable for time series data. \ue200cite\ue202turn0search1\ue201<\/li>\n<\/ol>\n\n\n\n
           proc sgplot data=Sales;\n       series x=Date y=Sales;\n       xaxis label='Date';\n       yaxis label='Sales';\n   run;<\/code><\/pre>\n\n\n\n
        In this code:<\/p>\n\n\n\n
          \n
        • proc sgplot data=Sales;<\/code> initiates the plotting procedure using the Sales<\/code> data set.<\/li>\n\n\n\n
        • series x=Date y=Sales;<\/code> plots the Sales<\/code> variable against Date<\/code>, connecting the points with lines.<\/li>\n\n\n\n
        • xaxis label='Date';<\/code> and yaxis label='Sales';<\/code> add labels to the x-axis and y-axis, respectively.<\/li>\n<\/ul>\n\n\n\n
          Explanation:<\/strong><\/p>\n\n\n\n
            \n
          • MDY Function:<\/strong> The MDY<\/code> function in SAS is used to create a SAS date value from separate month, day, and year variables. It takes three arguments: month, day, and year, and returns a SAS date value representing that specific date. For example, mdy(2, 28, 2025)<\/code> returns the SAS date value for February 28, 2025. \ue200cite\ue202turn0search2\ue201<\/li>\n\n\n\n
          • SAS Date Values:<\/strong> SAS stores dates as the number of days since January 1, 1960. This internal representation allows for efficient date calculations and comparisons. When you create a date variable using the MDY<\/code> function, SAS assigns it this numeric value, which can be formatted for display purposes.<\/li>\n\n\n\n
          • Time Series Plot:<\/strong> The SGPLOT<\/code> procedure is a versatile tool in SAS for creating various types of plots, including time series plots. The series<\/code> statement is specifically designed for time series data, as it connects data points with lines, making it easier to visualize trends over time. The xaxis<\/code> and yaxis<\/code> statements allow you to customize the labels of the axes for better clarity. \ue200cite\ue202turn0search1\ue201<\/li>\n<\/ul>\n\n\n\n
            By following these steps, you can effectively create a new date variable from existing components and visualize the sales data over time using a time series plot in SAS.<\/p>\n","protected":false},"excerpt":{"rendered":"
