Corner lot 地大。只和一家邻居紧连。隐私性更好。而且有地种pretty garden.
我在换房,我只买corner lot. 我老板家是corner lot. 真漂亮。
Model home is too expensive. I can not afford. 如果你能afford model home, 应该是好的选择。 Model home 的upgrades 很多。Most models are designed by professional interiour designers-very pretty. 可惜,我买不起。

出一款车不难,各大车厂譬如双田,大众等一年出很多款车, 卖得好也不难,关键
是要赚到钱!Model 3的花销多少,能不能赚到钱是股价会不会上涨的关键。 Model S
和X不赚钱就算了,但是Model 3 一定要赚到钱。 据说20万辆车的补贴额Tesla快用到
一半了,可能年底就耗尽了。 如果没有补贴,有没有愿意花3.5万来买Model 3? 很多
预订的人是冲着补贴而来。 另外最终多少人购买和预订量可能会少很多。 毕竟1000块
不是一个大数字。
现在搞得好像TSLA要直冲1000块,等着看吧!

任何一个产品的成功是基于市场的需求。苹果手机出现之前,手机市场已经形成很大的
规模,只是有点群龙无首,除了Motorola的Razor牛逼一阵后没有太出众的产品。 然后
苹果手机靠着独特的设计一下子奠定胜局。 电动车目前没有市场,Tesla现在做的事情
是创造这个市场。如果要拿两者来比的话, 那么如果在电动车市场已经形成一定规模
,但是缺乏有说服力的产品之时,Tesla可以靠一款优质产品一举拿下江山,那么这个
模式成功的概率会比较高,关键的是市场已经在那里摆着,谁想占领,凭本事做出牛逼
的产品就行。 而恰恰现在是没有市场,全球六大车厂也无意去推动电动车市场,那么
凭Tesla一己之力要改变汽车业就属于天方夜谭了。
至于Tesla的股价大涨就和Theranos的情况很相似,属于典型的炒作。 想当年
Elizabeth Holmes也是风光无限,个人资产达到45亿美元,结果呢? 碰到真正的挑战
,原形毕露,个人资产一夜间变零。 目前Tesla所谓的ER都毫无指导意义。我多次说过
, Model 3是Tesla能否成功的关键。Tesla根本没有遇到真正的考验,Model 3是否能

Model 3的定位是宝马3系和奔驰C系。它的性能比3系和C系要好一些,日常费用也少一
些,定价也还算合理。Model 3按MSRP卖,没有打折,实际上比3系和C系要贵一些。

历史总是会以惊人的方式重现!
你这个关于 model 3 的论调和 2012-2013年很多人对于 model S 的论调一摸一样。
实际上就 model X 那个丑了吧唧的面团加上一对屁用没有还老出问题的鹰翼门都
没能让 tesla 关门大吉.
马斯克过于激进的问题改不了,这可能是最终导致 tesla 资金链断裂被收购的原因。
但是 model 3 三年之内供不应求是板上钉钉的。

这个月2018 Charger SRT 392,假如通过US bank等这类IDL途径lease的话,FCA提供总

不过BMW 330i的性能比Model 3要差一些。如果选BMW 340i,性能好一些,MSRP是$54,

model 3 的设计非常超前,从UI 和噪音设计角度说。
没有cockpit (转速表等),一是简化降低成本; 2 是按照Musk的设计理念,这些不
需要,如不久能实现高度自动驾驶(只是不知何时)。
另外,model 3 非常安静,噪音比model S/X 低5-10分贝,原因是第三代的电机/齿轮
箱/逆变器的先进设计,效率、噪音、功率密度方面,远远超过model S/X。另外,空
调系统设计牛逼,出风口是一条线非常独特,HVAC风扇的功率小10w, 噪音低5分贝,但

“model 3 非常安静,噪音比model S/X 低5-10分贝”——你有必要在哪怕这种不重要

实话实说,虽然tesla不通过第三方dealer来卖车从而少了砍价环节的尔虞我诈。但是
tesla官方、还有某些粉丝,给人感觉十分不可信和奸诈,每一句话里面都带有圈套来

假如车厂官方做广告乱说话,那会惹上官司。但是培养众多粉丝来在各类非正式场合下

model 3刚生产了10万辆,市场就枯竭了?怎么可能。新产品刚刚上市,超过奔驰不算
啥,就不要提还有最初曾经到46万订单的需求,再等2个季度再看能不能超过奔驰。现
在这个时候tsla也不过才生产了20万辆车,每个星期才生产5000辆,总共才刚生产了10
万辆model 3,就已经不需要排队了,季报还没有赚过钱,46万的订单够tsla满载生产
一年半的,现在刚一个季度就没有了,都必须降价了。从那个方面衡量对得起它的市值
了?我觉得凡是故意忽略model 3曾经的46万预订,对于model 3一个季度5万辆的销量
表现出是个超出预期的神奇的成就,应该是有问题的判断。尤其是2年前用这个2个月就定
出46万得出无限美好的未来,支撑股价好几年,结果2年后,这个预约直接没有了,现
order就可以了,现在就换种解释说因为没有预订,销售了5万辆,太惊人了。这个数据

标 题: 特斯拉为什么要现在推出中程版本的Model 3
发信站: BBS 未名空间站 (Fri Oct 19 20:00:37 2018, 美东)
熊熊们大多认为,是因为高配版本的需求枯竭。这从某种程度上来说是正确的。毕竟,
在北美范围内(或是其他任何局部市场),六万美元均价的轿车的需求不可能那么高。
尽管Model 3已经抢了不少BBA的份额,但是在Q3发货接近六万辆以后,已经清掉了北美
市场高配订单的backlog,Q4很难收到同样数量的新订单。同时,Model 3的产能已经从
Q3的burst mode五千辆,逐渐提升到目前的每周稳定五千辆。也就是说即便产能在Q4不
再继续增长,也能季产65,000辆。在初期积累的需求被消化以后,如何调配产品的配置
选择,就很有讲究了。T要做的,是在供给、需求和利润之间找到一个最佳平衡。而供
给是由产能决定的。现在的假设是, Q4 Model 3的供给大于北美市场对Long Range(

谢谢你的回复。
如果我们不加kinship到model里,那么genotype就是一个有27个level的factor,R会
assume这些level是一样的,但其实它们之间的genetic distance并不一样,所以我们
想把这个信息加到model里。
让我困惑的就是怎么加。我想到一个办法就是把每个plant genotype跟其它所有
genotype的total genetic distance作为一个新的covariate放到model里。但我又觉得
,这个covariate和genotype不是collinear的吗?
plant breeding的人有时会把kinship matrix加到model里做association analysis。

Generally there are two ways of deriving the models for binary data:
1. latent variable approach: y*=x \beta + u. Here y* is a continuous
latent variable. then u can be treated as logistically or normally
distributed, which corresponds to logit or probit model. This approach is
modeling the underline variable behind the binary variable y.
2. link function approach. This approach models the binary variable y
directly: y=g(X \beta), where g() is the inverse link function. Basically
it maps

来自主题: EE版 - CMOS device or modeling
工作快2年了,做了1年半的CMOS device modeling,加半年多的CMOS device, 20nm
的,在NY的一家大型半导体公司,大家估计都知道。
最近在考虑换工作,现在有个机会,是一家RFIC的设计公司,做modeling/
simulation的,不过公司规模要小,在加州,地点是好很多。
比较纠结的是,职业发展方向到底是沿着device呢,还是modeling/simulation呢
? 搞device的,其实没几家公司了,就业范围比较窄,但是最近很多foundry/IDM 都
在大规模投资,貌似发展还可以。 如果转做modeling,很多fabless的公司会需要,但
是不值得前景会怎样,而去一旦转了,再回头就难了。
其实个人最理性的就是找个这两个都需要的职位,可惜opening就更少了。。。
听听大家的说法呢

大家好,我需要用mixed model 对三个group的人群(教育程度1,2,3)进行分析,看
看这些人的认知能力在不同时间的变化有没有显著性的不同。
proc mixed data=outban;
class timepoint educ;
model rbantotal= timepoint | educ/ solution;
random int /subject=id ;
lsmeans educ*timepoint;
run;
因为我是3个group,而不是两个group,如果我想看相互作用项educ*timepoint的p-值,
是不是需要用f-test?如何在mixed model中用f-test呢?我看到现在的结果里就已经有
f-test了:
