GetDeltaParamsVar function

Calculate Delta related parameters variance function

This function perform all needed calculations to get all Delta related parameters variance. For do the exact calculations some variables previously calculated are needed.

GetDeltaParamsVar(mx, fixedrows = FALSE, Delta, Pi, k, Cov, E)

Arguments

• mx: Matrix. Agreement contingency table to perform calculations
• fixedrows: Boolean. Indicate if sample rows are fixed beforehand.
• Delta: Vector. Each element indicate the probability of recognize an element i.
• Pi: Vector. Each element indicate the probability of classify at random an element in category i.
• k: Integer. Dimension of the problem.
• Cov: Matrix. Covariance matrix of Delta.
• E: Double. Value calculated for Cov matrix derivation.

Examples

GetDeltaParamsVar(mx = matrix(c(60,0,3,2,50,1,3,2,79),3,3), 
        fixedrows = FALSE,Delta = c( 0.8945724, 0.9522836, 0.8962094), 
     Pi = c( 0.2703707, 0.1939561, 0.5356732), k = 3, 
     Cov = matrix(c(0.002736490,  0.000004188, -0.001074704,
                0.000004188, 0.001141059, -0.000181746,
               -0.001074704, -0.000181746,  0.004912131),3,3),
        E = c(0.03159824,  0.01304313, -0.88650011))
