translate(ttime)
translate()所属R语言包:ttime
Translate neurodevelopmental event timing across species
翻译神经活动的时间跨越物种
译者:生物统计家园网 机器人LoveR
描述----------Description----------
The function translate predicts the unknown events using the model species score + event score = ln(post-conceptional day - k) proposed in (Finlay and Darlington 1995; Clancy et al., 2000; Nagarajan et al., 2010). The parameter k is estimated from the data by maximizing the correlation between the known and predicted events. A scatter plot of the empirical values and its predicted counterpart is also generated by this function. The adjusted R^2 is also shown in the plot.
功能翻译预测的未知事件利用该模型种类得分+事件得分= LN(概念后的一天 - K)(1995年芬利和达林顿Clancy等人,2000; Nagarajan等人,2010)提出的。参数k的估计从数据中的已知的和预测的事件之间的相关性最大化。经验值和预测对应的散点图,也会产生此功能。调整后的R ^ 2也显示在图中。
用法----------Usage----------
data(event_data);
translate(event_data, npsp)
参数----------Arguments----------
参数:event_data
A data frame containing the known and unknown neurodevelopmental event timing across species.
一个数据框包含已知和未知的神经活动不同物种间的时间。
参数:npsp
Number of non-primate species in event_data.
event_data非灵长类物种数。
Details
详细信息----------Details----------
A sufficient number of known events are necessary to obtain reliable predictions. The structure of input_vals should be the same as that of event_data.
足够数量的已知事件是必要的,以获得可靠的预测。的input_vals结构应该是的相同的event_data。
值----------Value----------
The known and predicted events along with their 95% confidence interval are returned in pred_vals.
随着其95%的置信区间的已知和预测的事件在pred_vals返回。

实例----------Examples----------
## Not run: [#不运行:]
library(ttime);
data(event_data); #event timing data[事件时序数据]
npsp <- 8; #number of non-primate species (npsp) in event_data[非灵长类物种数(NPSP)event_data]
pred_vals <- translate(event_data, npsp); #predicted events with 95% confidence interval[预测事件的95%置信区间]
## End(Not run)[#(不执行)]
