请教大家一下,我用时间以星期为单位去做销售的回归预测!

Y=A+BX 但是我得出的P值是大于0.05的

那么这就说明X对于Y的预测是没用的,那我可以得出 Y=A 吗??

我现在真的搞不明白,请大家帮忙了

Each statistical test has an associated null hypothesis, the p-value is the probability that your sample could have been drawn from the population(s) being tested (or that a more improbable sample could be drawn) given the assumption that the null hypothesis is true. A p-value of .05, for example, indicates that you would have only a 5% chance of drawing the sample being tested if the null hypothesis was actually true.

Null Hypothesis are typically statements of no difference or effect. A p-value close to zero signals that your null hypothesis is false.

Here p>0.05 does not mean accept null hypothesis, since 0.06 is still close to 0, and also cann't use for reject Null hypothesis.

Well,it depends on your hypothesis first.
