Webb22 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: WebbSteven is the founder of Top Tip Bio.
