Your hypothesis is that they change when the independent variable changes.

您假设是当自量发生化时它们会发生化。

To begin with, it may be useful to make clear which elements in the economic system we usually take as given, which are the independent variables of our system and which are the dependent variables.

首先，弄清楚我们通常认为经济系统中哪些要素是，哪些是我们系统自量，哪些是因量可能是有用。

Thus the traditional analysis is faulty because it has failed to isolate correctly the independent variables of the system. Saving and investment are the determinates of the system, not the determinants.

因此，传统分析是错误，因为它未能正确隔离系统自量。储蓄和投资是系统决因素，而不是决因素。

So we just showed you is that the variance of the difference of two independent random variables is equal to the sum of the variances.

所以我们刚刚展示是，独立随机量差差等于这差和。

And so what we're varying or the independent variable is going to be, the independent variable is going to be the amount of the enzyme.

因此，我们化或独立量将是酶量。

If we had speed as an independent variable, SAVE, and we measured based on outcomes, then I think that looks pretty different.

如果我们把速度作为一独立量，即SAVE， 并根据成果来衡量，那么我认为情况会大不相同。 这更像是执行层面操作。

We weren't able to agree on the appropriate independent variables.

我们无法就合适自量达成一致。

How did you measure your dependent and independent variables?

你如何测量你因量和自量?

In regression, y is the variable we want to predict (the dependent variable). In this example, y is the shear strength. x is the independent variable — in this case, the age of the propellant.

在回归中，y 是我们想要预测量（因量）。在此示例中，y 是剪切强度。 x 是自量——在本例中是推进剂年龄。

We used to have something called cost as an independent variable.

我们过去常把成本视为一独立量。

So we have one independent variable – receiving the voucher or not – and a bunch of possible dependent variables, like earnings, education, and health outcomes.

所以我们有一自量——是否收到代金券——以及一堆可能因量，比如收入、教育和健康结果。

And let's define it as the sum of 3 of these independent variables, each of them that have a standard normal distribution.

我们将它义为这三独立量和，每量都服从标准正态分布。

The factors, which we have taken as given, influence our independent variables, but do not completely determine them.

我们视为因素会影响我们自量，但不能完全决它们。

And since we're only taking one sum over here-- we're only taking the sum of one independent, normally distributed, standard or normally distributed variable, we say that this only has 1 degree of freedom.

因为我们这里只求了一总和——我们只是求了一独立标准正态分布量总和，所以我们说这只有1自由度。

The division of the determinants of the economic system into the two groups of given factors and independent variables is, of course, quite arbitrary from any absolute standpoint.

将经济系统决因素分为因素和自量组，当然，从任何绝对角度来看都是相当武断。

In this case, geographic location is what we call the independent variable; it’s the variable that we think is affecting the change in how people describe themselves.

在这种情况下，地理位置就是我们所说自量；我们认为这是影响人们自我描述式化量。

Our independent variables are, in the first instance, the propensity to consume, the schedule of the marginal efficiency of capital and the rate of interest, though, as we have already seen, these are capable of further analysis.

我们自量首先是消费倾向、资本边际效率表和利率，尽管正如我们已经看到那样，这些可以进一步分析。

But you can also have variables that you believe are affected by changes in your independent variable; these are your dependent variables.

但是您也可以拥有您认为受自量化影响量；这些是你因量。
