  • Ticket #666

    • Property Summary changed from BSR Fixing partial blocks to BSR Fixing and reloading partially for main linear block

  • Ticket #666 – Description

    initial v1  
    1 Some blocks are too intrincated to allow partial blocks but others, as linear block, could become faster if we can fix partially.
     1We can separate a linear regression block
     2
     3[[LatexEquation(Y = X \beta + e; e ~ N\left(0,I\right) $$)]][[BR]]
     4
     5in two sub-blocks
     6
     7[[LatexEquation(Y = X_{1} \beta_{1} +X_{2} \beta_{2} + e; e \sim N\left(0,I\right) $$)]][[BR]]
     8
     9If we have an inconditional sample or a fixed set of values for [[LatexEquation(\beta_{1} $$)]], then we can sample [[LatexEquation(\beta_{2} | \beta_{1} $$)]] from reduced regression
     10
     11[[LatexEquation(Y_1 = Y - X_{1} \beta_{1} = X_{2} \beta_{2} + e; e \sim N\left(0,I\right) $$)]][[BR]]
