The simple regression model (SRM) is model for association in the population between an explanatory variable X and response Y. The SRM states that these averages align on a line with intercept β0 and slope β1: µy|x = E(Y|X = x) = β0 + β1x Deviation from the Mean The deviation of observed responses around the conditional means µy|x are called errors (ε). The error’s equation: ε = y - µy|x Errors can be positive or negative‚ depending on whether data lie above (positive) or below the conditional

Methods of Estimation of flood discharge 4.1 Introduction After estimating the change in rainfall‚ as described in chapter 3‚ the next step is to convert that rainfall change into a flood flow (an amount of water flowing in a river). This chapter looks at both screening and advanced tools that can be used to help river managers estimate changes in flood flows. Historical data and ongoing data campaigns are vital components of any forecasts of flood flows. Although climate change means that future

2 Methode 2.1 Het lineaire regressiemodel Het lineaire regressiemodel wordt veel gebruikt binnen de economische wetenschap om situaties of gebeurtenissen te verklaren of te voorspellen. De relaties tussen verschillende variabelen worden door toepassing van dit regressiemodel verklaard. Wiskundig gezien wordt het lineaire regressiemodel als volgt weergegeven: Yt = α + βxt + ut. Y is de afhankelijke variabele‚ de onafhankelijke en verklarende variabele is x‚ α is een constante‚ β geeft de helling
