NettetYou could plot the residuals of your model against age - if you see an increase or decrease in variance associated with age, then you have non-constant error variance, and the assumptions of your regression model are violated.

High Low Method vs. Regression Analysis - Sample Calculations
NettetIn addition, you would need to identify outliers such as additive/pulse (one time event) or level shift (permanent shift) and add them as regressors. Identifying outliers in multiple regression for time series data is nearly impossible; you would need time series outlier detection methods such as Tsay's procedure or Chen and Liu's procedure ... NettetThe most popular form of regression is linear regression, which is used to predict the value of one numeric (continuous) response variable based on one or more predictor variables (continuous or categorical). Most people think the name “linear regression” comes from a straight line relationship between the variables. cafe kissako喫茶猫
