How to find the missing coefficient in a standard form equation. Similarly summary data for an outcome in a form that can be included in a meta-analysis may be missing. The standard form is ax² bx c 0 with a b and c being constants or numerical coefficients and x being an unknown variable. This is often a problem when change-from-baseline outcomes are sought.

You can remove the coefficient of 3 by dividing both parts of the equation to get x - 23 2 119. We discuss imputation of missing SDs in Chapter 6 Section 6528. The final equation is 3x - 23 2 113.

You have now successfully placed the equation into vertex form which is a x - h 2 k where k represents the constant term. Specifically the interpretation of β j is the expected change in y for a one-unit change in x j when the other covariates are held fixedthat is the expected value of the partial. Write the equation in vertex form.

A fitted linear regression model can be used to identify the relationship between a single predictor variable x j and the response variable y when all the other predictor variables in the model are held fixed.
