Dear STATA users, I wonder how I can compare the values of a variable, say var1, at different observations? (In particular I want to do regressions such as the one below) if var1(at line 2) = var1(at line 10 ) { regress y x in 2/10 } Thanks for suggestions, Sarah On 7/18...
Go to theInserttab and click onPivot table. Adialogue boxwill pop up. Select the table range and select a cell where the table will be. Click onOK. We will get another dialogue box. Check and drag theStatesandSales Channelto theRowandSales Unitin theValuessection. Excel will print the ...
Central to factor analysis, variance measures how much numerical values differ from the average. In factor analysis, you’re essentially trying to understand how underlying factors influence this variance among your variables. Some factors will explain more variance than others, meaning they more accura...
Enter this formula in cellF5: =SUM(IF(Date_Count(D5:D12)=7,1,0)) Press theCtrl + Shift + Enterkeys to apply it. This function will check date values in a given array or ranges andSUMthem one by one if the date value is valid. ...

In an additional robustness check (see Section 4.3.3), we analyze the impact of the sample reduction due to missing advertising and R&D expenses by imputing the missing values and find no substantive changes to the variables of interest. Lastly, after inspecting the value ranges for all ...
The fourth attribute presenting high importance is cleanliness, being significant in 14 market segments, with maximal values in Scity and Slow, and minimal values in Sma and Sfreq. Even though cost is significant in 14 market segments, its SMC are low in all the segments, which leaves it ...

sum of EXP values that have a SIC value begining with 20, i.e. 667.8039+130.8002+..+38.90306+0.617763 In others words I have some 4digit SIC data and I want to aggregate them into 2digit SIC. Any hint is really appreciated * * For searches and help try: *http://www.stata.com/...
