The data that you provide in the Excel file is insufficient. The notation implies that Drr, Apa and Grr are 3-dimensional arrays, and C and Csf are 1-dimensional arrays. The sigma formula says that we sum Drr*Apa*(C-Cnf) + Grr*Apa*(C-Csf)for eachi, j and k -- that is,for e...
目前的发展趋势来看,Sigmaplot 软件已落后 Origin Pro 太多,比如 Sigmaplot 没有外接 Google Map,无法处理地图数据。另外,Sigmaplot14.0 增加了对 OLE2 技术的支持,可以使用 Word 公式编辑器对图表进行注释,直接在 Word 或 PowerPoint 中编辑图形,或者在 SigmaPlot 内用 Excel 电...

NORMSINV is an Excel function that provides a Z value for a cumulative probability using a standard normal distribution. If you assume your data is normally distributed and are interested in knowing the Z value for a given probability, NORMSINV will provide that using the cumulative probabilities ...
By plugging in your scores you get the following: Verbal z = (630 – 469) ÷ 119 =1.35σ Quantitative z = (700 – 591) ÷148=.736σ To convert these sigma values into a percentage you can look them up in a standard z-table, use the Excel formula =NORMSDIST(1.35) or use theZ-...
The parts of the sigma notation in Figure 1 are as follows: The index of summation denotes the symbol being used in the formula for the summation. The starting index denotes the value of the index where the formula starts. The last index value denotes the final value of the index in the...
