mle_norm_eq_inc: MLE of NNT in equal sd Normal distribution
In vancak/NNT-calculator-2018: NNT Calculator

Internal function. Not for users. Takes two numeric vectors of control and treatment results and returns the MLE of the Laupacis' type NNT for Normal distribution with equal variances.

1 2	mle_norm_eq_inc(treat, control, tau, yt_bar, yc_bar, s_ml, p_t.boot, p_c.boot, s_ml.bs, n_c, n_t)

`treat`	a numeric vector of the treatment arm results

`tau`	a scalar that indicates the MCID
`yt_bar`	mean value of the treatment arm vector
`yc_bar`	mean value of the control arm vector
`s_ml`	sd of the the pooled variance MLE
`p_t.boot`	BS estimator of the sample proportion of success in the treatment arm
`p_c.boot`	BS estimator of the sample proportion of success in the control arm
`s_ml.bs`	BS estimator of the sd of the the pooled variance MLE
`n_c`	number of observations in the control arm
`n_t`	number of observations in the treatment arm
`p_c`	sample proportion of success in the control arm
`p_t`	sample proportion of success in the treatment arm
