Testing for independence (lack of correlation) of errors. Testing for homoscedasticity (constant variance) of errors. Testing for normality of the error distribution. There are four principal assumptions which justify the use of linear regression models for purposes of inference or prediction: (i) linearity and additivity of the relationship between dependent and independent variables:
Cephalexin can be used to treat infections that are caused by bacteria, including bone infections, skin infections, bladder infections, wounds and pneumonia. Like penicillin, Cephalexin for dogs kills bacteria in the body.
In some cases, many veterinarians may not prescribe cephalexin for a dog that has a urinary tract infection. Individuals could use the cephalexin for the infection with the 259 milligram dose. In most cases a urinary tract infection will go away in about 2 to 3 days after starting an antibiotic.
