```Dear fellows !

I have  300 values in radioactive-measurement in one column :
now I want to compute :

1)             - Tn = sum 1 to 300 [a(i).x(i)]             0 < alpha < 0.5
a(i) = 0
for i <= n1 or i >= n- n1 + 1
a(i) = (n1 + 1 -alpha*n)/((1 -2*alpha)*n)
for i = n1 + 1 or i = n - n1
a(i) = 1/((1-2*alpha)*n)
for n1 + 1 < i < n - n1

with : n1 = [alpha*n],n = 300
/ in europe we say L - estimator type I/

2)             - Tn = sum 1 to 300 [a(i).x(i)]             0 < alpha < 0.5
a(i) = (1/n)*[x(n1 +1)/x(i)]
for i <= n1
a(i) = 1/n
for n1 + 1 <= i <= n - n1
a(i) = (1/n)*[x(n - n1)/x(i)]
for i >= n - n1 +1

with : n1 = [alpha*n],n = 300
/ in europe we say L - estimator type II/

3)             - Tn = 0.25 *[x(n1 + 1) + x(n - n1)]  + 0.5*median-value
0 < alpha < 0.5

with : n1 = [alpha*n],n = 300

/ in europe we say trimean   /

4)             - Tn = 0.3 *[x(n1 + 1) + x(n - n1)]  + 0.4*median-value
0 < alpha < 0.5

/ in europe we say L - estimator type III/

5)if I create (x(i) + x(j))/2 that I get 300^2 values,I want to compute
median of this -
we say wilcoxon-appliance,I hope you will understand my terminologie
/ in europe we say L - estimator type IIII/

is there a command for all these values like lv-command for
sincerely,andreas aschbacher
