If Xt is a wide-sense stationary process then the mean Î¼ and the variance Ï2 are time-independent, and further the autocorrelation depends only on the lag between t and s: the correlation depends only on the time-distance between the pair of values but not on their position in time.
Febreze is classified as an air freshner, created by Proctor & Gamble. It reports to work by trapping odor molecules in a donut-shaped chemical. The first thing that is really important to understand: the product does not remove odor molecules and it doesn't clean the item it comes into contact with.
For that reason, I have created my DIY Homemade Febreze. At just $0.15 per bottle (That is not a typo!!!), I will never go back to buying this product from a store. In comparison to WalMartâs 27-ounce bottle for $4.99, the answer is clear.
