y*********m 发帖数: 33 | 2 recruiter发给我一道面试模拟题,是一个与能源有关的街里公司的面试题目。大家说
说这种【已知过去,预测未来】的典型题应该用什么方法呢?
方法肯定不只一种,我能想出来的只有time series,然后autoregressive。但是我的
统计、随机过程的知识少的可怜,所以肯定应该还有更合适的方法,拜托大家出出主意
,毕竟这里牛人多,而且大部分都是统计随机高手。
另外,弱弱地问:这个和stochastic differential equation(SDE)有关系么?
感激涕零~~~

to the extreme cold weather. The order took effect Wednesday morning, a day
after an ice and snow storm blanketed parts of Texas. Consumers and
businesses are urged to reduce their electricity use. ERCOT had no timetable
for when the rotating outages would end. The blackouts are not expected to
last more than 30- 45 minutes. The locations and durati... 阅读全帖 |

signature吗? 我现在的error是the primary signature must be encrypted。
我现在的function可以送request, 用fiddler我也可以看到response, 可是用他们的

j*****y 发帖数: 1916 | 11 In Texas, the power price increase was much smaller than the rest of the
nation, largely because of the mild weather this spring. The average
wholesale electricity price in the ERCOT Houston Zone was $35.33 per
megawatt-hour for the first half of 2013, up 13 percent from the year before
, according to the EIA.

如果1000度电成本才35美元。是不是电力公司转手就卖105美元,利润是不是有点离谱?
我也想去开一个皮包电力公司,给老中打7折。 |
