西半球

Multi tool use西半球是地球上本初子午线以西,180度经线以東的半球[1]。
由于歐洲及非洲的西部在西經,為避免被本初子午線分割,西半球及東半球的分界線有时也被定义为西經20°及東經160°。依照此分法,西半球的陸地有北美洲、南美洲、亞洲俄羅斯極東部、紐西蘭、南極洲部份、以及許多其他島嶼。太平洋東部、大西洋西部、以及北冰洋一部在西半球包圍北美洲及南美洲。
地理
西半球的中心位于太平洋,位于加拉帕戈斯群岛的第90个子午线西部和赤道的交汇处。最近的土地是捷诺维沙岛,位于0°19'00“N 89°57'00”W。
西半球最高的山峰是阿根廷安第斯山脉的阿空加瓜,海拔6,960.8米(22,837英尺)。

1 I having trouble getting my ResourceDictionary.MergedDictionaries to load from app.xaml. My WPF app has a static class with a Main defined and startup object set to it. Within Main I created an instance of App and run it. The override OnStartup fires and the mainwindow.cs InitializeComponent gives the error "Message "Cannot find resource named 'MaterialDesignFloatingActionMiniAccentButton'. If I put the resources in the mainwindow.xaml everything is fine, but I wanted them to load at the app level so I they are not in each page. Any help appreciated. public partial class App protected override void OnStartup(StartupEventArgs e) base.OnStartup(e); var app = new MainWindow(); var context = new MainWindowViewModel(); app.DataContext = context; app.Show(); from the Main.. var app = new App(); app.Run(); app.xaml.. <Application x:Class="GS.Server.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:...
up vote 2 down vote favorite There is a clear pattern that show for two separate subsets (set of columns); If one value is missing in a column, values of other columns in the same subset are missing for any row. Here is a visualization of missing data My tries up until now, I used ycimpute library to learn from other values, and applied Iterforest. I noted, score of Logistic regression is so weak (0.6) and thought Iterforest might not learn enough or anyway, except from outer subset which might not be enough? for example the subset with 11 columns might learn from the other columns but not from within it's members, and the same goes for the subset with four columns. This bar plot show better quantity of missings So of course, dealing with missings is better than dropping rows because It would affect my prediction which does contain the same missings quantity relatively. Any better way to deal with these ? [EDIT] The nullity pattern is confirmed: machine-learning cor...
