All queries in an SQL statement containing a UNION operator must have an equal number of expressions in their target lists. Change the first part of the query to a null or negative value so we can see what field will echo data back to us.


Stored NULL values are then displayed as [NULL] in column prod_id, and “NULL” values created by ROLLUP are replaced with ALL in column PROD_IDS, as Each subtotal row contains a NULL value in the column or columns over which the subtotal is computed. Row [1] represents the total number of...

There is, however, one problem with this method of naming number constants: You might inadvertently change the value of one of these variables. C++ provides a way of marking an initialized variable so that it cannot be changed. If your program tries to change one of these variables, it produces an error...


Panel Data using R
The null hypothesis in the LM test is that variances across entities is zero. This is, no significant difference across units (i.e. no panel effect). (http Here we failed to reject the null and conclude that random effects is not appropriate. This is, no evidence of significant differences across countries...
