Question

give the difference between anova, manova,mancova,pathanalysis,t-test,multiple regression and logistic regression

answrr only if you know otherwise dislike

Answer 1

1]t test is used for eqaulity of two samples.

2] ANOVA analysis of variances it is used for testing of equality of mean for more than 2 samples.

3]MANOVA is Multivariate analysis of variances. it is used for testing of equality of mean vector for more than 2 samples.

4]MANCOVA Multivariate analysis of co-variance it is used for testing of equality of mean vector for more than 2 samples.when we have one quantitative indepedent variable.

5]logistics regresion it is used for model bianary outcome it find condtitional expectation of binart outcome.

for binary outcome use binary logistics regression for multinominal outcome use multinominal logistic regression.

for ordinal outcome use ordinal logistic regression.

6]multiple regression it used for model continouse outcome

it is conditional expectation of continouse outcome while error of model follow n(m,simga) constant variances

7]Path analysis is used where you need to look at variables which can be exogenous and endogenous. In most models we assume that a variety of variables predict one or more variables, but in life we know that some variables predict others and those in turn predict others.
