Question

How do you find and interpret the least-squares multiple regression equation, with partial slopes?

Answer 1

You can always use programming language like R, matlab , to find partial slopes

Even Excel can be used

for example in R

model <- lm (y ~ x1+ x2+ ..xn)

summary(model)

summary(model) gives partial slopes .

for multiple linear regression in 2 variable

formulas are

partial slopes can be interpreted as when we change an independent variable by 1 unit keeping the other variable constant

then on averege there is change of partial slopes in dependent variable
