statistics - How do I calculate the CDF of the chi-square distribution in excel? -


does excell have function cdf of chi-square distribution?

if not how calculate manually?

i cant seem find i'm looking when try searching online. formula: enter image description here

i don't understand how plug values formula calculate result.

if have excel 2010 or later, there function this.

=chisq.dist(x, degrees_freedom, cumulative)

this function accepts 3 parameters:

  • x, value @ chi-square distribution calculated
  • degrees_freedom, number of degrees of freedom
  • cumulative, true or false conditional, false gives pdf , true gives cdf, you'd want true

you can read more microsoft.

if you're using excel 2007 or earlier, require more creativity excel's built in chi-square distribution functions right-tailed probabilities.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
