在Stata中出现“observation numbers out of range”错误通常是由于试图访问或操作不存在的观测值范围。 这个错误可能出现在多种情况下,比如绘图、数据访问或数据处理时。以下是一些可能的原因和解决方法: 检查数据范围: 确保你访问的数据范围在数据集中实际存在。例如,如果你试图访问第1000个观测值,但数据集只有500个观...
小白求教 不胜感激 天一生水0213 托儿所 1 set obs 2500//将观测值多设一点egen x1 = fill(1(1)2500)//生成2500个数字如果:set obs 50//设的太少,出现以下错误。egen x1 = fill(1(1)2500)observation numbers out of range。登录百度帐号 扫二维码下载贴吧客户端 下载贴吧APP看高清直播、视频!
Using our method, a single WWS can obtain large numbers of cross-correlation results for different δθ values. These diverse results can then be cross-referenced against each other, enhancing the performance of turbulence profiling. We selected 300 frames of our experimental measurements with each ...
Due to topological bulk-boundary correspondence, the values of (G0, Gπ) respectively determine the numbers of 0- and π-mode (or −π-mode) TCMs in the corners of this lattice. To confirm this, as exemplified in Fig. 2(f) for the phase (G0 = 1, Gπ = −1), we ...
By definition, sampling provides data for a subset of the population of behaviors and so is necessarily an imperfect representation of the population. All sampling methods misrepresent the source population in that sampling requires the transformation of larger numbers into smaller numbers. Because this...
The number of nearest neighbors for all three EdgeConv blocks is set to 6, with varying numbers of channels, specifically (8, 8, 8), (16, 16, 16), and (32, 32, 32), respectively. A channelwise global average pooling operation is applied after the EdgeConv blocks to aggregate the ...
1a. We selected four representative locations to study excitation dynamics, as indicated with colored ellipses with numbers 1 (outer corner site), 2 (site on the outer edge), 3 (site on the inner edge site) and 4 (inner corner site). For excitation we used pulses with a duration of ...
If one considers the numbers of levels s1,…,sk as given, better balance is not achievable. OAs of strength t exhibit such perfect balance at least in any tD projection, 1≤t≤m. This paper uses the term balance in a non-technical sense. It refers to the degree of perfection an ...

The numbers 1, 3 and 4 indicate the 1st, 3rd and 4th nearest neighbours, respectively, around a centre atom C. a, Plan view of a close-packed (111) plane, projected along the [112] beam direction. The distance between the nearest points in the [110] direction is r* (compare with ...
