What is the test for an appellant to prove that a purported error by the trial court prejudiced him?

Appellant also fails to explain how these purported errors prejudiced him. At minimum, appellant was required to show a " reasonable probability that in the absence of the [purported] error, a result more favorable to the appealing party would have been reached. " ( Adams v. MHC Colony Park, L.P. (2014) 224 Cal.App.4th 601, 614, 169 Cal.Rptr.3d 146.) In his briefing, appellant makes general claims of prejudice, and identifies some specific examples of purported errors by the trial court, but never explains how those errors affected the outcome of his case. These conclusory assertions of prejudice are insufficient. (See id. at p. 615, 169 Cal.Rptr.3d 146.)
