...,
and
c_(2N-1-k} = \sum_{j=0}^{N-1} a'_{2j} \cos{(2k+1)(j) \over 2N} \pi
- \sum_{j=0}^{N-1} a'_{2j+1} \cos{(2k+1)(2j+1) \over 4N} \pi
(otherwise).
Thus we calculate (for k = 0..N-1)
d_k := \sum_{j=0}^{N-1} a'_{2j} \cos{(2k+1)(j) \over 2N} \pi
(this is a half length DCT-II),
and
e_k := \sum_{j=0}^{N-1} a'_{2j+1} \cos{(2k+1)(2j+1) \over 4N} \pi
(a half length DCT-IV).
Hey, we know how to calculate those! Just recursion... The
endcase (startcase) for the recursion is the trivial summation
(N=1).
So, for calculating a MDCT:
Calculate a_j from x_j and w_j; now we need to c...

Variance Component/ICC Confidence Intervals via Bootstrap or Jackknife
I'm using the lme function in nmle to estimate the variance components
of a fully nested two-level model:
Y_ijk = mu + a_i + b_j(i) + e_k(j(i))
lme computes estimates of the variances for a, b, and e, call them v_a,
v_b, and v_e, and I can use the intervals function to get confidence
intervals. My understanding is that these intervals are probably not
that robust plus I need intervals on the intraclass correlation
coefficients:
v_a...
