How can I find the p-value (significance) of each coefficient? lm = sklearn.linear_model.LinearRegression() lm.fit(x,y)

How can I execute Little's Test, to find MCAR in Python? I have looked at the R package for the same test, but I want to do it in Python. Is there an alternate approach to test MCAR?

I am looking for a quick way to get the t-test confidence interval in Python for the difference between means. Similar to this in R: X1 <- rnorm(n = 10, mean = 50, sd = 10) X2 <- rnorm(n = 2...

so i have pasted my complete code for your reference, i want to know what's the use of ppf and cdf here? can you explain it? i did some research and found out that ppf(percent point function) is an...

I need to work with many hypothesis tests in R and present the results. Here is an example: > library(MASS) > h=na.omit(survey$Height) > > pop.mean=mean(h) > h.sample = sample(h,30...

I am currently trying to implement the Wilcoxon Ranksum test on multiple data sets that I've combined into one large matrix, A, that is 705x17635 (ie I want to run the ranksum test 17,635 times. Th...

To prepare a little toy example: import pandas as pd import numpy as np high, size = 100, 20 df = pd.DataFrame({'perception': np.random.randint(0, high, size), 'age': np.random.randint(0, high, ...

If I want to calculate the mean of two categories in Pandas, I can do it like this: data = {'Category': ['cat2','cat1','cat2','cat1','cat2','cat1','cat2','cat1','cat1','cat1','cat2'], 'values': [...

The Fisher's Exact Test is related to the hypergeometric distribution, and I would expect that these two commands would return identical pvalues. Can anyone explain what I'm doing wrong that they d...

When we have a linear model with a factor variable X (with levels A, B, and C) y ~ factor(X) + Var2 + Var3 The result shows the estimate XB and XC which is differences B - A and C - A. (suppose...

I met a problem of running a t-test for some data stored in a data frame. I know how to do it one by one but not efficient at all. May I ask how to write a loop to do it? For example, I have got t...

How do I specifically test the null and alternative hypothesis of the skewness and/or Kurtosis of a variable in hypothesis testing? Would I have to use a formula in t.test? t.test(data$variable,...

I have the following model: y = b1_group1*X1 + b1_group2*X1 + b2_group1*X2 + b2_group2*X2 + ... + b10_group1*X10 + b10_group2*X10 Easily made in R as follows: OLS <- lm(Y ~ t1:Group + t2:Gr...

I have a 94 varibles(sample+proteins+group) and 172 observations in a matrix as: Sample Protein1 Protein2 ... Protein92 Group 1 1.53 3.325 ... 5.63 0 2 2.32 3.451 ... 6.32 0 . . . 103 3.24 4.21 ....

I know that if I have a set of data, I can run t.test to do a T test. But I only know the count, mean and standard deviation for each set. I'm sure there must be a way to do this in R, but I can't ...

I'm using the R function ks.test() to test the Uniform distribution of the R random number generator. I'm using the following code: replicate(100000, ks.test(runif(n),y="punif"). When n is less th...

Suppose I have a large matrix: M <- matrix(rnorm(1e7),nrow=20) Further suppose that each column represents a sample. Say I would like to apply t.test() to each column, is there a way to do th...
