Linear equation for st
NettetDefinition. A first-order differential equation is linear if it can be written in the form. a(x)y ′ + b(x)y = c(x), (4.14) where a(x), b(x), and c(x) are arbitrary functions of x. Remember that the unknown function y depends on the variable x; that is, x is the independent variable and y is the dependent variable. Nettet22. jan. 2024 · Whenever we perform simple linear regression, we end up with the following estimated regression equation: ŷ = b 0 + b 1 x. We typically want to know if the slope coefficient, b 1, is statistically significant. To determine if b 1 is statistically significant, we can perform a t-test with the following test statistic: t = b 1 / se(b 1) where:
