What is the test for determining whether a judge abused his discretion by denying probation?

"'The circumstances utilized by the trial court to support its sentencing choice need only be established by a preponderance of the evidence. [Citations.]' [Citation.] Accordingly, in determining whether a trial court abused its discretion by denying probation, we consider, in part, whether there is sufficient, or substantial, evidence to support the court's finding that a particular factor was applicable." (Weaver, supra, 149 Cal.App.4th at p. 1313.) However, a trial court does not abuse its discretion unless its decision is so irrational or arbitrary that no reasonable person could agree with it, and this court is neither authorized nor warranted in substituting our judgment for that of the trial judge. (People v. Carmony (2004) 33 Cal.4th 367, 376-377.)
