Determines the range of dispersion of the values.
strayval = ST_strayarea(v, p)
vector of numerical values
statistical confidence level (%) as a string or the level of significance (alpha) as a decimal value, "95%", "99%", "99.9%" or 0.05, 0.01, 0.001 resp (see examples).
stray area, range of dispersion of the values.
"ST_strayarea" determines the range of dispersion of the values. It describes the quality of the raw values.
E.g. if strayval = 1.4 at p = 95% with a mean = 10,0 all raw values of the whole population will be expected with a confidence of 95% at about 10.0 +/- 1.4.
V = [6 8 14 12 5 15]; mean(V) // = 10. strayval1 = ST_strayarea(V, "95%") // = 10.904 strayval2 = ST_strayarea(V, 0.05) // = 10.904 | ![]() | ![]() |
