transfer p value to z value

Hello! I have p values (i.e. accuracy in %), how can I transfer these p values to corresponding Z values in standard normal distribution ? is there any function I can use?

for example, p = 0.95, Z = 1.645 in POZ conversion table.

Thanks a lot in advance!

best!

Hello,

I think you can take a look here

Answer 1

[David Hill]

If you have the Statistics and Machine Learning Toolbox the function is norminv(). If you don't, the documentation for the norminv function gives you enough information to write your own function.

z = norminv(.95);

Use the norminv function.

If you do not have the Statistics and Machine Learning Toolbox, y9ou can use this anonymous function:

ZV = @(pv) -sqrt(2) * erfcinv(2*pv);        % Equivalent to ‘norminv’
