Modeling - Delta Response

16.12.2020

Multinomial Flight Modeling Flight Trials Winter 2020 were conducted from 2/17/2020 - 3/10/2020. Soapberry bugs were flight tested twice (T1 vs. T2) for multiple hours in the flight mill and observed from 8 AM to (5-8 PM) each day. I used multicategorical, nominal modeling (multinom) to analyze how sex and host plant as well as changes in mass a...

Time Series - Wing Data

06.04.2021

Introduction When to use a time series vs. a linear regression? If you have continuous target variable, then it is a regression problem. For instance, in flight trials we have the flight distance to predict, which is continuous. Hence this becomes a regression problem. About time series, when the datapoints are time dependent, then it becomes a ...

Delta Distance Modeling All Bugs Problems Noticing qqplots of all models are not normal and the best fit model is the null model for all. Might need to retransform the distance_diff data either by standardizing it or performing another transformation. (NOTE: only did analyses for bugs that flew and had a distance > 0.)
