actuaryzhang 1aeb9f6cba [SPARK-19400][ML] Allow GLM to handle intercept only model ... ## What changes were proposed in this pull request? Intercept-only GLM is failing for non-Gaussian family because of reducing an empty array in IWLS. The following code `val maxTolOfCoefficients = oldCoefficients.toArray.reduce { (x, y) => math.max(math.abs(x), math.abs(y))` fails in the intercept-only model because `oldCoefficients` is empty. This PR fixes this issue. yanboliang srowen imatiach-msft zhengruifeng ## How was this patch tested? New test for intercept only model.
