What is the legal test for admitting or excluding expert testimony at trial?

"A trial court's decision to admit or exclude expert testimony is reviewed for abuse of discretion. [Citation.]" (People v. Pearson (2013) 56 Cal.4th 393, 443.) Under that standard, we will not disturb the trial court's decision unless it was arbitrary, capricious, or patently absurd resulting in a manifest miscarriage of justice. (People v. Rodriguez (1999) 20 Cal.4th 1, 9-10.)
