Oct 14, 2016 · This post demonstrates how to create new variables, recode existing variables and label variables and values of variables. We use variables of the census.dta data come with Stata as examples.-generate-: create variables. Here we use the -generate- command to create a new variable representing population younger than 18 years old.
A one-variable data table contain its input values either in a single column (column-oriented), or across a row (row-oriented). Any formula in a one-variable data table must refer to only one input cell. Follow these steps: Type the list of values that you want to substitute in the input cell—either down one column or across one row.
One Variable Data Table. To create a one variable data table, execute the following steps. 1. Select cell B12 and type =D10 (refer to the total profit cell). 2. Type the different percentages in column A. 3. Select the range A12:B17. We are going to calculate the total profit if you sell 60% for the highest price, 70% for the highest price, etc. 4.
The correct value for the variable used in the solution, specified as any of the supported data types. Structures, tables and cells containing only the supported data types are also allowed. Data types datetime, duration, and calendarDuration ignore any applied formatting.
A one-variable data table contain its input values either in a single column (column-oriented), or across a row (row-oriented). Any formula in a one-variable data table must refer to only one input cell.
Using data tables makes it easy to examine a range of possibilities at a glance. Because you focus on only one or two variables, results are easy to read and share in tabular form. A data table cannot accommodate more than two variables. If you want to analyze more than two variables, you should instead use scenarios.
What-if analysis is the process of changing the values in cells to see how those changes will affect the outcome of formulas on the worksheet.
If you want to analyze more than two variables, you should instead use scenarios. Although it is limited to only one or two variables ( one for the row input cell and one for the column input cell), a data table can include as many different variable values as you want.
Use a one-variable data table if you want to see how different values of one variable in one or more formulas will change the results of those formulas.
