WebbIn statistics, ordinary least squares (OLS) is a type of linear least squares method for choosing the unknown parameters in a linear regression model (with fixed level-one effects of a linear function of a set of explanatory variables) by the principle of least squares: minimizing the sum of the squares of the differences between the observed … WebbHypothesis Test for Regression Slope. This lesson describes how to conduct a hypothesis test to determine whether there is a significant linear relationship between an independent variable X and a dependent variable Y.. The test focuses on the slope of the regression line Y = Β 0 + Β 1 X. where Β 0 is a constant, Β 1 is the slope (also called the regression … ipad 1st gen accessories
