In this paper, we suggest how to handle the issue of heteroskedasticity measurement errors when specifying dynamic models for conditional expectation realized variance. We show that either adding a GARCH correction within an asymmetric extension HAR class ( AHAR - ), or working multiplicative error AMEM ) greatly reduces need quarticity/quadratic terms capture attenuation bias. This feature in ...
