Palmitoyl Oligopeptide (also known as palmitoyl pentapeptide, Dermaxyl, Matrixyl and Matrixyl 3000) is an engineered amino-peptide that when added to a culture of fibroblasts (key skin cells), stimulates collagen, elastin and glucosaminoglycans production. These are the key components of healthy-looking skin.

All Answers (8) In simple linear regression the equation of the model is. y = b0 + b1 * x + error. The b0 and b1 are the regression coefficients, b0 is called the intercept, b1 is called the coefficient of the x variable. Significance tests compare the above model with the following models: 0: y = 0 + B1 * x + error. 1: y = B0 + 0 * x + error. The significance test of the intercept thus compares the intercept to 0, thus it tests whether the the regression line goes through the origin (x=0, y=y).
