Altum AI predicts the transaction value or free sale value for the given valuation date.
The AVM learns to predict house valuations from the actual market values. Once the prediction is generated, the process of estimating the prediction interval starts. The prediction interval divulges where a value will fall in the future and is a great way to estimate uncertainty. This procedure is constructed by a statistical approach which defines a price range for where the 90% confidence interval lies.
The AVM API as default uses the date of today of entry. It is possible to input a valuation date in the past and then the AVM API will return the value of that given date. It is not possible to give valuations for future dates, if a future date is given as input it will return the valuation for 'today'.
House number additions are combined with house letters as follows: B4
The model has a Median Absolute Performance Error rate of 3.57%. Go to the on the Altum AI website for a more in depth explanation (Dutch).
If the valuation date which is given as an input is for example 10-10-2019 we give the WOZ value applicable and distributed for that year which is the WOZ-value from 1-1-2018.
