# How to obtain regression coefficients of a multiple linear regression model from simple linear regression models? [duplicate]

Suppose I have a multiple linear regression model $$Y=\beta_0+\beta_1X_1+\cdots+\beta_pX_p+\epsilon$$ How can I obtain the regression coefficients $$\hat{\beta_i}$$ by fitting just a series of simple linear regression models (additionally using sample means of the response/predictor variables if needed)?
