通俗理解T检验与F检验的区别

1. T检验和F检验的由来
一般而言,为了确定从样本(sample)统计结果推论至总体时所犯错的概率,我们会利用统计学家所开发的一些统计方法,进行统计检定。
 
通过把所得到的统计检定值,与统计学家建立了一些随机变量的概率分布(probability distribution)进行比较,我们可以知道在多少%的机会下会得到目前的结果。倘若经比较后发现,出现这结果的机率很少,亦即是说,是在机会很少、很罕有的情况下才出现;那我们便可以有信心的说,这不是巧合,是具有统计学上的意义的(用统计学的话讲,就是能够拒绝虚无假设null hypothesis,Ho)。相反,若比较后发现,出现的机率很高,并不罕见;那我们便不能很有信心的直指这不是巧合,也许是巧合,也许不是,但我们没能确定。
 
F值和t值就是这些统计检定值,与它们相对应的概率分布,就是F分布和t分布。统计显著性(sig)就是出现目前样本这结果的机率。

Origin无法一次性打开已保存的opj格式文件解决方法

Origin是科研人员最常用的画图软件了,但是你有没有碰到当双击之前保存的.opj文件的时候,第一次打开是空白的,重新再打开就正常了的情况呢?也就是说在软件冷启动的情况下,不能直接打开已有文件。经过摸索,发现解决方法很简单,如下:

在.opj文件上右键,选择打开方式,然后选择软件安装文件夹下的可执行文件即可,记得勾选以后默认都用这个打开哦。

出现这个问题可能是默认链接的打开程序哪里出了问题。

作为一个有追求的科研党,电脑上必备哪些软件?

操作简单、专业性强、能够节省效率的工具可以让科研工作事半功倍。作为教师,发表核心期刊的论文,想办法追求高效率的科研是必须的。

以下这几款软件可以大大提高你的工作学习效率,尤其是对科研工作大有裨益:

1  基本配置:Office Word、PPT、Excel

Office几乎是电脑的标配,有什么好推荐的?这里要说的是Office每一次更新版本都增加了强大的新功能,会提供更好的使用体验,提高效率。 继续阅读

Fortran 语法备忘录 (高级)

  • 混合语言编程  Mixed-Language-Programming
    用Fortran调用C++语言的程序
    例如一个简单的C++语言程序,求直角三角形斜边长度的达哥拉斯公式:保存为crout.cpp文件。
    !———————————————————————–
    // C++ – Routine
    #include <iostream.h>
    #include <math.h>
    extern “C” void pythagoras (float a, float b, float *c)
    {
    *c = (float) sqrt(a*a+b*b);
    }
    !———————————————————————–
    注:如果用C语言,则用stdio.h代替iostream.h,并且不需要extern “C”,其余过程类似。
