Value assignement to SQD<br />
For each time t, each of the 10 parameters of SQD is the random variable taking<br />
the value 1 if the property is fulfilled and 0 if it is missing.<br />
Each parameters is characterised by an estimation of the expected value and by an estimation<br />
of its variance. For the computation a linear approximation is chosen.<br />
SQD i (t) = a i,j t + b i,j<br />

The SQD is an xlm data structure containing for all 10 SQD parameters, for different upcoming<br />
time intervals, the coefficients of an linear approximation of the expected value and and of the<br />
standard deviation of the parameters.<br />
