# Seasonality Core 2.7.2

Seasons are only available to freshly created characters who must be leveled all the way from level 1 after the season begins. Seasonal characters have a separate stash, gold and other currencies, artisans, Paragon experience etc., starting fresh and completely clear when the season begins. These are also separate for Softcore and Hardcore Seasonal characters, making a total of four types per account.[3] Seasonal characters take up one of the regular 12 or 15 character slots and will remain in this slot after the end of a Season, simply having their Season status removed.[4]

## Seasonality Core 2.7.2

The PTR for Patch 2.7.2 began on Thursday, November 4, 2021. Season 25 introduced a new type of socketable item called Soul Shards. Nephalem could find 7 unique Soul Shards, based on the Lords of Hell, which give players demonic new powers. One of 3 Prime Evil Soul Shards could be equipped into Helms and one of 4 Lesser Evil Soul Shards could be equipped into Weapons. Each Soul Shard could be upgraded three times using a new seasonal-exclusive consumable, the Hellforge Ember.[79] The season began on December 10, 2021[56] and ended on April 10, 2022.[57]

rpy2 package will automatically dive into "bin" folder to call R.exe; however, the core R files are located one level below (64-bit: bin\x64 or 32-bit: bin\i386). For example, assuming you wish to use 64-bit R, to make RPY2 work properly, you need to make sure that you copy everything , except R.exe and Rscript.exe, from the x64 folder to the bin folder.

Inliers are labeled 1, while outliers are labeled -1. The predict methodmakes use of a threshold on the raw scoring function computed by theestimator. This scoring function is accessible through the score_samplesmethod, while the threshold can be controlled by the contaminationparameter.

Note that neighbors.LocalOutlierFactor does not supportpredict, decision_function and score_samples methods by defaultbut only a fit_predict method, as this estimator was originally meant tobe applied for outlier detection. The scores of abnormality of the trainingsamples are accessible through the negative_outlier_factor_ attribute.

If you really want to use neighbors.LocalOutlierFactor for noveltydetection, i.e. predict labels or compute the score of abnormality of newunseen data, you can instantiate the estimator with the novelty parameterset to True before fitting the estimator. In this case, fit_predict isnot available.

When novelty is set to True be aware that you must only usepredict, decision_function and score_samples on new unseen dataand not on the training samples as this would lead to wrong results.I.e., the result of predict will not be the same as fit_predict.The scores of abnormality of the training samples are always accessiblethrough the negative_outlier_factor_ attribute.

The neighbors.LocalOutlierFactor (LOF) algorithm computes a score(called local outlier factor) reflecting the degree of abnormality of theobservations.It measures the local density deviation of a given data point with respect toits neighbors. The idea is to detect the samples that have a substantiallylower density than their neighbors.

In practice the local density is obtained from the k-nearest neighbors.The LOF score of an observation is equal to the ratio of theaverage local density of its k-nearest neighbors, and its own local density:a normal instance is expected to have a local density similar to that of itsneighbors, while abnormal data are expected to have much smaller local density.

When applying LOF for outlier detection, there are no predict,decision_function and score_samples methods but only a fit_predictmethod. The scores of abnormality of the training samples are accessiblethrough the negative_outlier_factor_ attribute.Note that predict, decision_function and score_samples can be usedon new unseen data when LOF is applied for novelty detection, i.e. when thenovelty parameter is set to True, but the result of predict maydiffer from that of fit_predict. See Novelty detection with Local Outlier Factor.

To use neighbors.LocalOutlierFactor for novelty detection, i.e.predict labels or compute the score of abnormality of new unseen data, youneed to instantiate the estimator with the novelty parameterset to True before fitting the estimator:

Natural external forcing also results from explosive volcanism that introduces aerosols into the stratosphere (Section 2.7.2), leading to a global negative forcing during the year following the eruption. Several reconstructions are available for the last two millennia and have been used to force climate models (Section 6.6.3). There is close agreement on the timing of large eruptions in the various compilations of historic volcanic activity, but large uncertainty in the magnitude of individual eruptions (Figure 6.13). Different reconstructions identify similar periods when eruptions happened more frequently. The uncertainty in the overall amplitude of the reconstruction of volcanic forcing is also important for quantifying the influence of volcanism on temperature reconstructions over longer periods, but is difficult to quantify and may be a substantial fraction of the best estimate (e.g., Hegerl et al., 2006a).

Prior to applying a forecasting method, the data may requirepre-processing. There are basic details, such as checking for accuracyand missing values. Other matters might precede the application of theforecasting method or be incorporated into the methods/modelsthemselves. The treatment of seasonality is such a case. Someforecasting method/models require de-seasonalised time series, whileothers address seasonality within the methods/models. Making it lessclear when seasonality is considered relative to a forecastingmethod/model, some governmental statistical agencies produce forecaststo extend time series into the future in the midst of estimatingseasonal factors (i.e., X-12 ARIMA).

Once a SS system is fully specified, the core problem is to provideoptimal estimates of states and their covariance matrix over time. Thiscan be done in two ways, either by looking back in time using thewell-known Kalman filter (useful for online applications) or takinginto account the whole sample provided by smoothing algorithms (typicalof offline applications) (B. D. O. Anderson & Moore, 1979).

In the state-of-the-art demographic forecasting, the core engine isprovided by matrix algebra. The most common approach relies on thecohort-component models, which combine the assumptions on fertility,mortality and migration, in order to produce future population by age,sex, and other characteristics. In such models, the deterministicmechanism of population renewal is known, and results from the followingdemographic accounting identity (Bryant & Zhang, 2018; population balancing equation, see Rees & Wilson, 1973):\[P[x+1, t+1] = P[x, t] - D[(x, x+1), (t, t+1)]+ I[(x, x+1), (t, t+1)] - E[(x, x+1), (t, t+1)]\]

To overcome the curse of dimensionality (see also2.2.5,2.5.2 and2.5.3), a dimension reduction technique,such as functional principal component analysis (FPCA), is often used.Aue, Norinho, & Hörmann (2015) showed asymptotic equivalence between a FAR and a VAR model(for a discussion of VAR models, see2.3.9). Via an FPCA, Aue et al. (2015)proposed a forecasting method based on the VAR forecasts of principalcomponent scores. This approach can be viewed as an extension ofR. J. Hyndman & Shang (2009), in which principal component scores are forecast via aunivariate time series forecasting method. With the purpose offorecasting, Kargin & Onatski (2008) proposed to estimate the FAR(1) modelby using the method of predictive factors. Johannes Klepsch & Klüppelberg (2017) proposed a functionalmoving average process and introduced an innovations algorithm to obtainthe best linear predictor. J. Klepsch, Klüppelberg, & Wei (2017) extended the VAR model to the vectorautoregressive moving average model and proposed the functionalautoregressive moving average model. The functional autoregressivemoving average model can be seen as an extension of autoregressiveintegrated moving average model in the univariate time series literature(see2.3.4).

The density forecast is based on the uncertainty derived by the Bayesianestimation and it is commonly evaluated using the probability integraltransform and the log predictive density scores (Kolasa & Rubaszek, 2015a; as main references, Wolters, 2015). The statistical significance ofthese predictions is evaluated using the Amisano & Giacomini (2007) test thatcompares log predictive density scores from two competing models.

In the Bayesian setup, forecasting model performance is typicallyevaluated based on a \(K\)-fold out-of-sample log predictive score (LPS: Geweke & Amisano, 2010), and out-of-sample Value-at-Risk (VaR) orExpected Shortfall (ES) are particularly used in financial applications.The LPS is an overall forecasting evaluation tool based on predictivedensities, serving out-of-sample probabilistic forecasting. LPS is idealfor decision makers(Geweke, 2001; Geweke & Amisano, 2010). The VaR gives thepercentile of the conditional distribution, and the corresponding ES isthe expected value of response variable conditional on it lying belowits VaR. 041b061a72
