Calculates the slope and offset of the line obtained by linear regression analysis (least squares method).

Obtain the slope and offset of the line calculated using the least squares method from c(1,3,4,6,7,10) and c(5.7,10.4,11.1,19.5,21.8,26.2).

var vData = c(c(1,3,4,6,7,10), c(5.7,10.4,11.1,19.5,21.8,26.2));
var vResult = ::Math.LineSt(vData);
var a = vResult[0]; // a (slope) of Y = aX + b
var b = vResult[1]; // b (offset) of Y = aX + b
