Definition of a p-value. How to use a p-value in a hypothesis test. Find the value on a TI 83 calculator. Hundreds of how-tos for stats.
? 2) How does Matlab compute the p-value? The p-value(which should be smaller than the critical value of the F statistic in order to have a significant test) is normally the area beneath the right tail of the f distribution at the F-value, if I understood ...
compute t-stats and p-values after qreg. I adapted the bootstrap code to stata 9, but got an error message. Is something wrong with the syntax or is stata 9 to be handled differently? Bonus Question: Is there a simpler way of obtaining t-stats and p-values in stata 9? many thanks!
Step 3: Multiply the values in each column. (In other words, multiply each value of X by each probability P(X).) Referring to our probability distribution table: 0 × .95 = 0 1 × .02 = .02 2 × .02 = .04 3 × .01 = .03 Step 4: Add the results from...
Unless your goal is to somehow improve on what is already written, or you simply don't have those existing tools, then you should never be reinventing the wheel. Use existing code, for example, regress is in the stats toolbox. Or you could even use my polyfitn f...
In this step-by-step tutorial, you'll learn the fundamentals of descriptive statistics and how to calculate them in Python. You'll find out how to describe, summarize, and represent your data visually using NumPy, SciPy, pandas, Matplotlib, and the built
To move to the desired functions key the first letter of its name (without keying ALPHA first). The function's syntax is displayed in the status line. All further mention of the functions assumes they are being used from the Stats/List Editor screen. Managing Lists Using the List Editor p...

P-values can be calculated from a cumulative distribution (norm.cdf()fromscipy.stats) which represents the probability of obtaining a value equal to orless thanthe one observed. Then to calculate the p-value we calculate1 - norm.cdf()to find the probabilitygreater thanthe one observed:...
