    UC Merced Land Use Dataset These images were manually extracted from large images from the USGS National Map Urban Area Imagery collection for various urban areas around the US. This is a 21 class land use image dataset meant for research purposes. There are 100 images for each class. 2,100 Image chips of 256x256, 30 cm (1 foot) GSD

    where A t is the actual value and F t is the forecast value. Their difference is divided by the actual value A t. The absolute value of this ratio is summed for every forecasted point in time and divided by the number of fitted points n.

    When the model has been estimated over all available data with none held back, the MSPE of the model over the entire population of mostly unobserved data can be estimated as follows.

    The UK House Price Index replaced this release in June 2016.[3] Historically, HM Land Registry also published a separate house price index calculated by Calnea Analytics. It used the HM Land Registry’s data, which consists of the transaction records of all residential property sales in England and Wales. It uses Repeat Sales Regression.

  7. Null distribution - Wikipedia

    en.wikipedia.org/wiki/Null_distribution

    Null distribution is a tool scientists often use when conducting experiments. The null distribution is the distribution of two sets of data under a null hypothesis. If the results of the two sets of data are not outside the parameters of the expected results, then the null hypothesis is said to be true. Null and alternative distribution

  8. Prediction interval - Wikipedia

    en.wikipedia.org/wiki/Prediction_interval

    Given a sample from a normal distribution, whose parameters are unknown, it is possible to give prediction intervals in the frequentist sense, i.e., an interval [a, b] based on statistics of the sample such that on repeated experiments, X n+1 falls in the interval the desired percentage of the time; one may call these "predictive confidence intervals".

    The same dataset plotted in three charts: Top panel is a bar chart depicting the flow of occurrences over time (resembles the Sankey diagram in the New York Times original [36]). Middle panel is a bubble chart that separately quantifies discrete outcomes.
