Pulled from the referenced article:
[font="Times New Roman"][ @skipchecks = ] 'skipchecks'
Specifies whether to skip or run UPDATE STATISTIC. skipchecks is a nvarchar(10) value, with a default value of NULL. To skip UPDATE STATISTICS, specify true. To explicitly run UPDATE STATISTICS, specify false.
By default, UPDATE STATISTICS is performed to update information about the data in the tables and indexes. Performing UPDATE STATISTICS is useful for databases that are to be moved to read-only media.[/font]
It seems to me running the base command is the same as adding the skipchecks=false option.
