math.linearModelCoeff

math.linearModelCoeff(
   linear-model as math.linearModel
) as Sequence

Summary

Returns the coefficients of the linear model. Currently only simple linear regression model is supported so the return should contain only one coefficient (also called "slope").

Example

var arr = new Array();
for (i=1; i < 11; i++) { 
  var x = new Array();
  var j = 2 * i + 1;
  x.push(j, i);
  arr.push(x); };
var lm = math.linearModel(xdmp.arrayValues(arr));
math.linearModelCoeff(lm);
