CFA Practice Question

Given SSE = 30, SST = 120, n = 18, k = 3, compute adjusted R2.
Correct Answer: 0.6964

R2 = 1 - SSE/SST = 0.75.
Adjusted R2 = 1 - [(18 - 1)/(18 - 3 - 1)] (1 - R2) = 0.6964.

danlan2 Adjusted R^2
=1-(n-1)*SSE/((n-k-1)*SST)
=1-17*30/(14*120)=39/56
=0.6964
MasterD Adjusted R^2 == Rbar^2

Rbar^2 = 1 - (n-1)/(n-k-1) * [1-R^2]

Substitute R^2 = 1-SSE/SST you get

Rbar^2 = 1 - (n-1)/(n-k-1) * [1-(1-SSE/SST)]
= 1 - (n-1)/(n-k-1) * [SSE/SST]

Rbar^2 = 1 - (n-1)/(n-k-1) * [SSE/SST]
= 1 - (18-1)/(18-3-1) * [30/120]
= 0.6964
